1
00:00:00,000 --> 00:00:07,000
Vale, vamos a grabar la clase correspondiente al sistema métrico decimal, ¿vale?

2
00:00:07,000 --> 00:00:12,000
Sistema es porque las cosas están unidas entre sí y funcionan juntas.

3
00:00:12,000 --> 00:00:16,000
Un sistema, tengo un sistema respiratorio porque tengo órganos

4
00:00:16,000 --> 00:00:19,000
que funcionan juntos para poder respirar.

5
00:00:19,000 --> 00:00:24,000
Yo tengo un sistema circulatorio porque tengo partes de mi cuerpo

6
00:00:24,000 --> 00:00:27,000
que funcionan juntas para que mi sangre pueda circular

7
00:00:27,000 --> 00:00:30,000
y hay intercambio de alimentos, de oxígeno, vale.

8
00:00:30,000 --> 00:00:33,000
Pues un sistema son cosas que funcionan juntas.

9
00:00:33,000 --> 00:00:35,000
Un sistema mecánico es un reloj.

10
00:00:35,000 --> 00:00:39,000
Es un sistema, un conjunto de piezas que funcionan juntas,

11
00:00:39,000 --> 00:00:46,000
cada una con su rol para yo poder leer la medida de tiempo, por ejemplo, ¿vale?

12
00:00:46,000 --> 00:00:51,000
Entonces, eso es un sistema, conjunto de cosas que funcionan juntas.

13
00:00:51,000 --> 00:00:53,000
Métrico, ¿de dónde viene métrico?

14
00:00:53,000 --> 00:00:55,000
De la palabra griega métrica que es medida.

15
00:00:55,000 --> 00:00:58,000
Es decir, estoy cogiendo un sistema para medir, ¿vale?

16
00:00:58,000 --> 00:01:01,000
Y decimal, porque mi base es 10.

17
00:01:01,000 --> 00:01:04,000
¿De cuándo creéis que es el metro?

18
00:01:04,000 --> 00:01:10,000
¿De cuándo creéis que es el metro?

19
00:01:10,000 --> 00:01:18,000
¿De los romanos?

20
00:01:18,000 --> 00:01:27,000
¿De los romanos?

21
00:01:27,000 --> 00:01:31,000
¿De cuándo es el metro?

22
00:01:31,000 --> 00:01:33,000
No sé, di lo que tú quieras.

23
00:01:33,000 --> 00:01:36,000
Apuesta, tú di lo que quieras.

24
00:01:36,000 --> 00:01:38,000
¿De los egipcios?

25
00:01:38,000 --> 00:01:39,000
De los egipcios, vale.

26
00:01:39,000 --> 00:01:43,000
Coged el móvil y buscad el metro cuándo se instituyó.

27
00:01:43,000 --> 00:01:59,000
¿De cuándo es el metro?

28
00:01:59,000 --> 00:02:10,000
La próxima cámara.

29
00:02:10,000 --> 00:02:28,000
¿Cuándo se define el metro?

30
00:02:28,000 --> 00:02:31,000
Ostras, había llegado.

31
00:02:31,000 --> 00:02:33,000
1889.

32
00:02:33,000 --> 00:02:37,000
Estamos hablando antes de ayer.

33
00:02:37,000 --> 00:02:40,000
Y hasta entonces no había metro.

34
00:02:40,000 --> 00:02:42,000
Se medía con partes del cuerpo.

35
00:02:42,000 --> 00:02:43,000
No existía el metro.

36
00:02:43,000 --> 00:02:45,000
Se medía con palmos, se medía con pies,

37
00:02:45,000 --> 00:02:48,000
se medía con yardas, se medía con celemines,

38
00:02:48,000 --> 00:02:51,000
se medía con varas, pero no existía el metro.

39
00:02:51,000 --> 00:02:52,000
¿Vale?

40
00:02:52,000 --> 00:02:58,000
Entonces, es de 1889.

41
00:02:58,000 --> 00:03:00,000
En un congreso que se hace.

42
00:03:00,000 --> 00:03:02,000
¿Qué sucede en el mundo en esa época?

43
00:03:02,000 --> 00:03:05,000
¿Qué época histórica es?

44
00:03:05,000 --> 00:03:10,000
¿A partir de 1850 qué se da?

45
00:03:10,000 --> 00:03:14,000
No, después de Cristo.

46
00:03:14,000 --> 00:03:18,000
¿Qué surge a partir de mediados del XIX?

47
00:03:18,000 --> 00:03:20,000
Cuando pensáis en mediados del XIX,

48
00:03:20,000 --> 00:03:21,000
¿qué os viene a la mente?

49
00:03:21,000 --> 00:03:25,000
¿Qué imágenes os vienen a la mente?

50
00:03:25,000 --> 00:03:27,000
La revolución industrial.

51
00:03:27,000 --> 00:03:28,000
Fábricas.

52
00:03:28,000 --> 00:03:31,000
Y las fábricas se hacen porque hay máquinas.

53
00:03:31,000 --> 00:03:32,000
¿Vale?

54
00:03:32,000 --> 00:03:34,000
¿Qué pasa si construimos una máquina?

55
00:03:34,000 --> 00:03:36,000
¿Las máquinas se hacen solo de una cosa?

56
00:03:36,000 --> 00:03:40,000
¿O las construyen muchas o diferentes empresas?

57
00:03:40,000 --> 00:03:42,000
Pensad en un coche.

58
00:03:42,000 --> 00:03:47,000
¿Construye una sola fábrica todas las piezas del coche?

59
00:03:47,000 --> 00:03:48,000
No, ¿verdad?

60
00:03:48,000 --> 00:03:51,000
¿Le pide a unos una cosa, a otros otra?

61
00:03:51,000 --> 00:03:52,000
¿Vale?

62
00:03:52,000 --> 00:03:55,000
¿Qué pasa si yo te encargo, por ejemplo, que midas?

63
00:03:55,000 --> 00:03:56,000
Yo mido mi mesa.

64
00:03:56,000 --> 00:03:58,000
Medir es coger la unidad y medir.

65
00:03:58,000 --> 00:04:02,000
Ver cuántas veces mi patrón entra en lo que voy a medir.

66
00:04:02,000 --> 00:04:07,000
Si mido con palmos, ¿cuánto mide esta mesa conmigo?

67
00:04:08,000 --> 00:04:09,000
No llega.

68
00:04:09,000 --> 00:04:10,000
Tres y tres cuartos.

69
00:04:10,000 --> 00:04:11,000
Vale.

70
00:04:11,000 --> 00:04:13,000
¿Y si ahora lo mides tú?

71
00:04:20,000 --> 00:04:22,000
¿Cuatro y medio?

72
00:04:22,000 --> 00:04:23,000
Cuatro y medio.

73
00:04:23,000 --> 00:04:27,000
Vale, tenemos un problema porque si yo te digo que tú me hagas una mesa

74
00:04:27,000 --> 00:04:30,000
de tres palmos y tres cuartos

75
00:04:30,000 --> 00:04:33,000
y tú usas tu medida, ¿qué te va a pasar?

76
00:04:33,000 --> 00:04:36,000
Que vas a hacer más pequeña.

77
00:04:36,000 --> 00:04:39,000
Que vas a hacer la mesa más pequeña.

78
00:04:39,000 --> 00:04:43,000
Y yo tengo un problema porque no me encajan las piezas que tengo que poner.

79
00:04:43,000 --> 00:04:45,000
Por eso se hace necesario unificar todas las medidas

80
00:04:45,000 --> 00:04:48,000
y todos los países europeos, que son los industrializados,

81
00:04:48,000 --> 00:04:51,000
deciden ponerse de acuerdo y utilizar todos el mismo sistema de medidas

82
00:04:51,000 --> 00:04:52,000
que es el metro.

83
00:04:52,000 --> 00:04:56,000
Y para eso cogen algo que es común a todos, que es la tierra.

84
00:04:57,000 --> 00:05:00,000
Y como cogen el radio de la tierra, el perímetro de la tierra,

85
00:05:00,000 --> 00:05:03,000
que siempre es el mismo, pero es una medida muy grande porque, claro,

86
00:05:03,000 --> 00:05:06,000
yo no puedo medir la mesa en perímetros de la tierra.

87
00:05:06,000 --> 00:05:10,000
Entonces cogen una subdivisión, una diezmillonesima parte

88
00:05:10,000 --> 00:05:13,000
y sale el metro, la medida.

89
00:05:13,000 --> 00:05:15,000
¿Lo entendemos?

90
00:05:15,000 --> 00:05:17,000
Pero es de antes de ayer.

91
00:05:17,000 --> 00:05:18,000
El metro es de antes de ayer.

92
00:05:18,000 --> 00:05:20,000
Nosotros llevamos midiendo toda la vida.

93
00:05:20,000 --> 00:05:24,000
Pero cuando se hace de verdad necesario un sistema métrico

94
00:05:24,000 --> 00:05:26,000
para todos, que nos unifique a todos

95
00:05:26,000 --> 00:05:29,000
y que funcione con todas las magnitudes que medimos,

96
00:05:29,000 --> 00:05:31,000
surge el metro.

97
00:05:31,000 --> 00:05:36,000
En una convención que es la de las medidas en París.

98
00:05:37,000 --> 00:05:38,000
¿Vale?

99
00:05:38,000 --> 00:05:39,000
Antes de ayer.

100
00:05:39,000 --> 00:05:41,000
Porque 1850 está...

101
00:05:41,000 --> 00:05:43,000
O sea, 1890 está ya al lado.

102
00:05:43,000 --> 00:05:45,000
¿Lo entendemos?

103
00:05:45,000 --> 00:05:49,000
Porque no tiene sentido ver un sistema

104
00:05:49,000 --> 00:05:51,000
si no sé qué estoy mirando y por qué.

105
00:05:52,000 --> 00:05:53,000
¿Ha quedado claro?

106
00:05:53,000 --> 00:05:55,000
Por eso surge la Revolución Industrial.

107
00:05:55,000 --> 00:05:58,000
Las matemáticas no van aparte de la realidad.

108
00:05:58,000 --> 00:06:01,000
Las matemáticas dan respuesta a las necesidades de la irrealidad

109
00:06:01,000 --> 00:06:03,000
en cada momento de la historia.

110
00:06:03,000 --> 00:06:06,000
Por eso la trigonometría y las curvas se desarrollan

111
00:06:06,000 --> 00:06:08,000
después de la navegación,

112
00:06:08,000 --> 00:06:11,000
después del siglo de los descubrimientos en el XVI,

113
00:06:11,000 --> 00:06:14,000
o aquí las medidas cogen muchísima fuerza

114
00:06:14,000 --> 00:06:17,000
y establecer un sistema de medidas igual para todos

115
00:06:17,000 --> 00:06:19,000
coja muchísima fuerza en el XIX

116
00:06:19,000 --> 00:06:21,000
porque estamos en plena Revolución Industrial

117
00:06:21,000 --> 00:06:23,000
Yo le tengo que decir a Funalito

118
00:06:23,000 --> 00:06:26,000
mándame una barra que mida tanto

119
00:06:26,000 --> 00:06:27,000
y a Menganito

120
00:06:27,000 --> 00:06:30,000
oye, y tú engrana con una tuerca que tenga este diámetro.

121
00:06:31,000 --> 00:06:32,000
¿Ha quedado claro?

122
00:06:33,000 --> 00:06:34,000
¿Vale?

123
00:06:34,000 --> 00:06:36,000
Y no podemos usar medidas corporales

124
00:06:36,000 --> 00:06:38,000
porque todos tenemos cuerpos distintos

125
00:06:38,000 --> 00:06:40,000
que era lo que hasta entonces siempre había funcionado.

126
00:06:41,000 --> 00:06:42,000
¿De acuerdo?

127
00:06:42,000 --> 00:06:45,000
Por eso se establece un sistema métrico decimal.

128
00:06:45,000 --> 00:06:46,000
¿Por qué decimal?

129
00:06:46,000 --> 00:06:49,000
Porque nosotros ya tenemos instaurado un sistema de numeración.

130
00:06:49,000 --> 00:06:52,000
¿Cómo funciona nuestro sistema de numeración?

131
00:06:56,000 --> 00:06:58,000
Si yo te digo 328,4

132
00:07:12,000 --> 00:07:13,000
¿Qué órdenes tengo?

133
00:07:13,000 --> 00:07:14,000
¿Qué lugares tengo?

134
00:07:14,000 --> 00:07:16,000
¿Cómo llamo a los lugares?

135
00:07:16,000 --> 00:07:18,000
¿Dónde tengo la coma?

136
00:07:19,000 --> 00:07:21,000
Yo voy a poner aquí la coma.

137
00:07:21,000 --> 00:07:23,000
Luego este cuadrito, ¿qué me marca?

138
00:07:24,000 --> 00:07:26,000
Unidades, muy bien.

139
00:07:29,000 --> 00:07:31,000
¿Y hacia abajo?

140
00:07:31,000 --> 00:07:34,000
Si hago la unidad dividida en 10 partes

141
00:07:34,000 --> 00:07:36,000
porque necesito meter algo muy pequeño

142
00:07:36,000 --> 00:07:38,000
o sea, porque necesito contar algo muy pequeño

143
00:07:38,000 --> 00:07:40,000
décima

144
00:07:41,000 --> 00:07:43,000
La voy a poner así.

145
00:07:46,000 --> 00:07:48,000
Entonces el 8 lo pondría aquí

146
00:07:48,000 --> 00:07:50,000
y el 4 lo pondría aquí.

147
00:07:51,000 --> 00:07:52,000
¿Y luego?

148
00:07:53,000 --> 00:07:54,000
Centésimas

149
00:07:54,000 --> 00:07:55,000
¿Centésimas?

150
00:07:55,000 --> 00:07:56,000
¿Y luego?

151
00:07:56,000 --> 00:07:57,000
Milésimas

152
00:07:57,000 --> 00:08:01,000
Y cada una va teniendo 10 veces de las anteriores.

153
00:08:01,000 --> 00:08:03,000
Si yo quiero las equivalencias

154
00:08:03,000 --> 00:08:06,000
una de cada una va teniendo 10 veces de las anteriores.

155
00:08:06,000 --> 00:08:08,000
Si yo quiero las equivalencias

156
00:08:08,000 --> 00:08:10,000
Si yo quiero las equivalencias

157
00:08:10,000 --> 00:08:12,000
una unidad son 10 décimas.

158
00:08:12,000 --> 00:08:14,000
¿Vale?

159
00:08:14,000 --> 00:08:15,000
Multiplico por 10

160
00:08:15,000 --> 00:08:17,000
para saber cuántas décimas tengo en una unidad

161
00:08:17,000 --> 00:08:19,000
lo que yo hago es coger la coma

162
00:08:19,000 --> 00:08:21,000
y decir, ¿dónde quiero la coma ahora?

163
00:08:23,000 --> 00:08:24,000
Aquí

164
00:08:24,000 --> 00:08:25,000
porque quiero saber

165
00:08:25,000 --> 00:08:27,000
mi unidad ahora van a ser las décimas

166
00:08:27,000 --> 00:08:28,000
¿Cuántas décimas tengo?

167
00:08:28,000 --> 00:08:29,000
¿Cuántas décimas tengo?

168
00:08:29,000 --> 00:08:30,000
84

169
00:08:31,000 --> 00:08:33,000
Y si yo pongo aquí las...

170
00:08:34,000 --> 00:08:35,000
¿Qué hay en el otro lado?

171
00:08:35,000 --> 00:08:36,000
Los múltiplos

172
00:08:39,000 --> 00:08:40,000
¿En el otro lado?

173
00:08:45,000 --> 00:08:46,000
¿Qué tengo aquí?

174
00:08:47,000 --> 00:08:48,000
¿Después de la unidad?

175
00:08:50,000 --> 00:08:51,000
No, antes

176
00:08:51,000 --> 00:08:52,000
esos son 100

177
00:08:52,000 --> 00:08:54,000
100 unidades es la centena

178
00:08:54,000 --> 00:08:55,000
10 unidades

179
00:08:55,000 --> 00:08:57,000
10 es la...

180
00:08:57,000 --> 00:08:59,000
10

181
00:09:00,000 --> 00:09:01,000
¿De qué?

182
00:09:01,000 --> 00:09:03,000
Decenas

183
00:09:05,000 --> 00:09:06,000
10

184
00:09:06,000 --> 00:09:07,000
Ah, decenas

185
00:09:07,000 --> 00:09:08,000
10

186
00:09:09,000 --> 00:09:10,000
Y centena

187
00:09:12,000 --> 00:09:13,000
Unidad de mil

188
00:09:15,000 --> 00:09:16,000
¿Vale?

189
00:09:16,000 --> 00:09:17,000
Decena de mil

190
00:09:17,000 --> 00:09:18,000
Centena de mil

191
00:09:18,000 --> 00:09:19,000
Eso lo hemos hablado

192
00:09:19,000 --> 00:09:20,000
¿Os acordáis?

193
00:09:20,000 --> 00:09:21,000
¿Vale?

194
00:09:21,000 --> 00:09:22,000
Pues pondría aquí el 2

195
00:09:22,000 --> 00:09:23,000
y aquí el 3

196
00:09:23,000 --> 00:09:24,000
Y si yo te pidiera

197
00:09:24,000 --> 00:09:25,000
este número

198
00:09:25,000 --> 00:09:28,000
que son 328,4 unidades

199
00:09:32,000 --> 00:09:33,000
Te dijera

200
00:09:33,000 --> 00:09:35,000
¿Cuántas centenas son?

201
00:09:38,000 --> 00:09:40,000
¿Cuántas centenas tienes?

202
00:09:41,000 --> 00:09:42,000
Tres y un poco, ¿no?

203
00:09:42,000 --> 00:09:43,000
Sí

204
00:09:43,000 --> 00:09:44,000
¿Qué estás haciendo con la coma?

205
00:09:45,000 --> 00:09:46,000
Moverla

206
00:09:46,000 --> 00:09:47,000
¿Moverla a dónde?

207
00:09:48,000 --> 00:09:50,000
A las centenas

208
00:09:50,000 --> 00:09:51,000
Porque te he pedido

209
00:09:51,000 --> 00:09:53,000
¿Cuántas centenas tienes?

210
00:09:53,000 --> 00:09:54,000
¿Ha quedado claro?

211
00:09:54,000 --> 00:09:55,000
Vale

212
00:09:55,000 --> 00:09:56,000
¿Sí?

213
00:09:56,000 --> 00:09:57,000
Sí

214
00:09:57,000 --> 00:09:58,000
¿Vale?

215
00:09:58,000 --> 00:09:59,000
Pues es exactamente

216
00:09:59,000 --> 00:10:00,000
lo que pasa con las unidades

217
00:10:00,000 --> 00:10:01,000
Dicen, si tenemos un sistema

218
00:10:01,000 --> 00:10:02,000
que funciona

219
00:10:02,000 --> 00:10:03,000
vamos a hacer que con las unidades

220
00:10:03,000 --> 00:10:04,000
me pase lo mismo

221
00:10:04,000 --> 00:10:05,000
Entonces, yo voy a tener

222
00:10:05,000 --> 00:10:06,000
una unidad de medida

223
00:10:06,000 --> 00:10:07,000
bien de longitud

224
00:10:07,000 --> 00:10:08,000
bien de capacidad

225
00:10:08,000 --> 00:10:09,000
bien de peso

226
00:10:09,000 --> 00:10:10,000
de masa

227
00:10:10,000 --> 00:10:11,000
¿Vale?

228
00:10:11,000 --> 00:10:12,000
La unidad de masa

229
00:10:12,000 --> 00:10:13,000
Entonces

230
00:10:13,000 --> 00:10:14,000
Nosotros

231
00:10:14,000 --> 00:10:15,000
¿En qué medimos

232
00:10:15,000 --> 00:10:16,000
la longitud?

233
00:10:16,000 --> 00:10:17,000
En la medida

234
00:10:17,000 --> 00:10:18,000
Lo primero que instauramos

235
00:10:18,000 --> 00:10:19,000
es la base de la medida

236
00:10:19,000 --> 00:10:20,000
porque si cogimos

237
00:10:20,000 --> 00:10:21,000
el perímetro de la Tierra

238
00:10:21,000 --> 00:10:22,000
que es una longitud

239
00:10:22,000 --> 00:10:23,000
pues la medida

240
00:10:23,000 --> 00:10:24,000
es exactamente

241
00:10:24,000 --> 00:10:25,000
la base de la medida

242
00:10:25,000 --> 00:10:26,000
¿Vale?

243
00:10:26,000 --> 00:10:27,000
Entonces

244
00:10:27,000 --> 00:10:28,000
la medida

245
00:10:28,000 --> 00:10:29,000
es exactamente

246
00:10:29,000 --> 00:10:30,000
la base de la medida

247
00:10:30,000 --> 00:10:31,000
¿Vale?

248
00:10:31,000 --> 00:10:32,000
Entonces

249
00:10:32,000 --> 00:10:33,000
la medida

250
00:10:33,000 --> 00:10:34,000
es exactamente

251
00:10:34,000 --> 00:10:35,000
pues la medida

252
00:10:35,000 --> 00:10:36,000
es el metro

253
00:10:36,000 --> 00:10:37,000
Así que yo funciono

254
00:10:37,000 --> 00:10:38,000
con el metro

255
00:10:38,000 --> 00:10:39,000
en longitud

256
00:10:39,000 --> 00:10:40,000
Si yo tengo capacidad

257
00:10:40,000 --> 00:10:41,000
lo voy a llamar

258
00:10:41,000 --> 00:10:42,000
litro

259
00:10:42,000 --> 00:10:43,000
y si yo tengo masa

260
00:10:43,000 --> 00:10:44,000
la voy a llamar

261
00:10:44,000 --> 00:10:45,000
gramo

262
00:10:45,000 --> 00:10:46,000
y estas tres

263
00:10:46,000 --> 00:10:47,000
están relacionadas

264
00:10:47,000 --> 00:10:48,000
luego lo vamos a ver

265
00:10:48,000 --> 00:10:49,000
¿Vale?

266
00:10:49,000 --> 00:10:50,000
Entonces

267
00:10:50,000 --> 00:10:51,000
primero definen el metro

268
00:10:51,000 --> 00:10:52,000
pero independientemente

269
00:10:52,000 --> 00:10:53,000
de cuál de las tres sea

270
00:10:53,000 --> 00:10:54,000
lo que yo hago

271
00:10:54,000 --> 00:10:55,000
es coger

272
00:10:55,000 --> 00:10:56,000
mi unidad

273
00:10:56,000 --> 00:10:57,000
y la pongo aquí

274
00:10:57,000 --> 00:10:58,000
¿Vale?

275
00:10:58,000 --> 00:10:59,000
Entonces

276
00:10:59,000 --> 00:11:00,000
primero definen el metro

277
00:11:00,000 --> 00:11:01,000
pero independientemente

278
00:11:01,000 --> 00:11:02,000
de cuál de las tres sea

279
00:11:02,000 --> 00:11:03,000
lo que yo hago

280
00:11:03,000 --> 00:11:04,000
es coger

281
00:11:04,000 --> 00:11:05,000
mi unidad

282
00:11:05,000 --> 00:11:06,000
y la pongo aquí

283
00:11:06,000 --> 00:11:07,000
¿Vale?

284
00:11:07,000 --> 00:11:08,000
Entonces

285
00:11:08,000 --> 00:11:09,000
decenacente

286
00:11:09,000 --> 00:11:10,000
en la unidad de millar

287
00:11:10,000 --> 00:11:11,000
son prefijos

288
00:11:11,000 --> 00:11:12,000
que vienen del latín

289
00:11:12,000 --> 00:11:13,000
¿Qué hacen

290
00:11:13,000 --> 00:11:14,000
para las medidas?

291
00:11:14,000 --> 00:11:15,000
Coger prefijos del latín

292
00:11:15,000 --> 00:11:16,000
Entonces

293
00:11:16,000 --> 00:11:17,000
en lugar de

294
00:11:17,000 --> 00:11:18,000
dec

295
00:11:18,000 --> 00:11:19,000
utilizaré

296
00:11:19,000 --> 00:11:20,000
el prefijo

297
00:11:20,000 --> 00:11:21,000
teca

298
00:11:21,000 --> 00:11:22,000
En lugar

299
00:11:22,000 --> 00:11:23,000
de

300
00:11:23,000 --> 00:11:24,000
cente

301
00:11:24,000 --> 00:11:25,000
extra

302
00:11:25,000 --> 00:11:26,000
teca

303
00:11:26,000 --> 00:11:27,000
en lugar

304
00:11:27,000 --> 00:11:28,000
de

305
00:11:28,000 --> 00:11:29,000
cente

306
00:11:29,000 --> 00:11:30,000
extra

307
00:11:30,000 --> 00:11:31,000
teca

308
00:11:31,000 --> 00:11:32,000
en lugar

309
00:11:32,000 --> 00:11:33,000
de

310
00:11:33,000 --> 00:11:34,000
hecto

311
00:11:44,000 --> 00:11:45,000
y en lugar

312
00:11:45,000 --> 00:11:46,000
de unidad de millar

313
00:11:46,000 --> 00:11:48,000
kilo

314
00:11:48,000 --> 00:11:50,000
y va de tres en tres

315
00:11:50,000 --> 00:11:52,000
entonces

316
00:11:52,000 --> 00:11:53,000
luego ya

317
00:11:53,000 --> 00:11:54,000
dejo dos huecos

318
00:11:54,000 --> 00:11:55,000
bueno

319
00:11:55,000 --> 00:11:56,000
aquí la siguiente

320
00:11:56,000 --> 00:11:57,000
se suele usar

321
00:11:57,000 --> 00:11:58,000
también

322
00:11:58,000 --> 00:11:59,000
es el miria

323
00:12:03,000 --> 00:12:04,000
pero ya no seríamos

324
00:12:04,000 --> 00:12:05,000
a ir de tres en tres

325
00:12:05,000 --> 00:12:06,000
¿Vale?

326
00:12:07,000 --> 00:12:08,000
Esto sería

327
00:12:08,000 --> 00:12:09,000
diez a la tres

328
00:12:09,000 --> 00:12:10,000
diez a las seis

329
00:12:10,000 --> 00:12:11,000
sería

330
00:12:11,000 --> 00:12:12,000
mega

331
00:12:12,000 --> 00:12:13,000
diez a la nueve

332
00:12:13,000 --> 00:12:14,000
sería giga

333
00:12:14,000 --> 00:12:15,000
diez a la doce

334
00:12:15,000 --> 00:12:16,000
es decir

335
00:12:16,000 --> 00:12:17,000
sería

336
00:12:17,000 --> 00:12:18,000
tera

337
00:12:18,000 --> 00:12:19,000
cada tres

338
00:12:19,000 --> 00:12:20,000
porque si ya estoy

339
00:12:20,000 --> 00:12:21,000
en tan grande

340
00:12:21,000 --> 00:12:22,000
no necesito

341
00:12:22,000 --> 00:12:23,000
pasar de uno en uno

342
00:12:23,000 --> 00:12:24,000
ya son medidas

343
00:12:24,000 --> 00:12:25,000
muy grandes

344
00:12:25,000 --> 00:12:26,000
y con tener una

345
00:12:26,000 --> 00:12:27,000
cada tres órdenes

346
00:12:27,000 --> 00:12:28,000
de magnitud

347
00:12:28,000 --> 00:12:29,000
más o menos me llega

348
00:12:29,000 --> 00:12:30,000
¿Vale?

349
00:12:30,000 --> 00:12:31,000
Entonces

350
00:12:32,000 --> 00:12:33,000
kilo

351
00:12:33,000 --> 00:12:34,000
tres más

352
00:12:34,000 --> 00:12:35,000
mega

353
00:12:35,000 --> 00:12:36,000
tres más

354
00:12:36,000 --> 00:12:37,000
giga

355
00:12:37,000 --> 00:12:38,000
tres más

356
00:12:38,000 --> 00:12:39,000
tera

357
00:12:39,000 --> 00:12:40,000
¿Dónde usamos

358
00:12:40,000 --> 00:12:41,000
esas unidades tan grandes?

359
00:12:41,000 --> 00:12:42,000
Pues ahora mismo

360
00:12:42,000 --> 00:12:43,000
solamente en el almacenamiento

361
00:12:43,000 --> 00:12:44,000
informático

362
00:12:44,000 --> 00:12:45,000
y en la potencia

363
00:12:45,000 --> 00:12:46,000
eléctrica

364
00:12:46,000 --> 00:12:47,000
gigavatios

365
00:12:48,000 --> 00:12:49,000
megavatios

366
00:12:49,000 --> 00:12:50,000
he gastado

367
00:12:50,000 --> 00:12:51,000
ocho megavatios

368
00:12:51,000 --> 00:12:52,000
este mes

369
00:12:53,000 --> 00:12:55,000
un neurogenerador

370
00:12:55,000 --> 00:12:56,000
genera

371
00:12:56,000 --> 00:12:57,000
gigavatios

372
00:12:57,000 --> 00:12:58,000
y no hay más

373
00:12:59,000 --> 00:13:00,000
para

374
00:13:00,000 --> 00:13:01,000
que tienes que ir

375
00:13:01,000 --> 00:13:02,000
a las unidades

376
00:13:02,000 --> 00:13:03,000
de almacenamiento

377
00:13:03,000 --> 00:13:04,000
informático

378
00:13:04,000 --> 00:13:05,000
¿Por qué te crees

379
00:13:05,000 --> 00:13:06,000
que dices?

380
00:13:06,000 --> 00:13:07,000
Es un disco

381
00:13:07,000 --> 00:13:08,000
de dos teras

382
00:13:09,000 --> 00:13:10,000
no son teras

383
00:13:10,000 --> 00:13:11,000
son terabandes

384
00:13:12,000 --> 00:13:13,000
¿Ha quedado claro?

385
00:13:13,000 --> 00:13:14,000
Vale

386
00:13:14,000 --> 00:13:15,000
y para abajo

387
00:13:15,000 --> 00:13:16,000
claro

388
00:13:16,000 --> 00:13:17,000
evidentemente

389
00:13:17,000 --> 00:13:18,000
con la unidad

390
00:13:23,000 --> 00:13:24,000
y para abajo

391
00:13:24,000 --> 00:13:25,000
en lugar de décima

392
00:13:25,000 --> 00:13:26,000
deci

393
00:13:27,000 --> 00:13:28,000
estas son las que

394
00:13:28,000 --> 00:13:29,000
se mantienen igual

395
00:13:29,000 --> 00:13:30,000
en lugar de décima

396
00:13:30,000 --> 00:13:31,000
deci

397
00:13:31,000 --> 00:13:32,000
en lugar de centésima

398
00:13:34,000 --> 00:13:35,000
centi

399
00:13:35,000 --> 00:13:36,000
y en lugar de milésima

400
00:13:36,000 --> 00:13:37,000
mili

401
00:13:50,000 --> 00:13:51,000
¿Vale?

402
00:13:51,000 --> 00:13:52,000
Entonces

403
00:13:52,000 --> 00:13:53,000
si yo te digo

404
00:13:54,000 --> 00:13:55,000
que tengo

405
00:13:55,000 --> 00:13:56,000
328,4

406
00:14:00,000 --> 00:14:01,000
metros

407
00:14:01,000 --> 00:14:02,000
perdón

408
00:14:02,000 --> 00:14:03,000
se me ha juntado

409
00:14:08,000 --> 00:14:09,000
que es una M

410
00:14:10,000 --> 00:14:11,000
¿Tú dónde vas a poner

411
00:14:11,000 --> 00:14:12,000
la coma?

412
00:14:12,000 --> 00:14:13,000
Me estás diciendo

413
00:14:13,000 --> 00:14:14,000
que tienes

414
00:14:14,000 --> 00:14:18,000
328,4 metros

415
00:14:18,000 --> 00:14:19,000
¿Tu cifra

416
00:14:19,000 --> 00:14:20,000
de las unidades

417
00:14:20,000 --> 00:14:21,000
quién es?

418
00:14:22,000 --> 00:14:23,000
¿Tu cifra

419
00:14:23,000 --> 00:14:24,000
de las unidades?

420
00:14:24,000 --> 00:14:25,000
El ocho

421
00:14:25,000 --> 00:14:26,000
y me estás diciendo

422
00:14:26,000 --> 00:14:27,000
que este ocho

423
00:14:27,000 --> 00:14:28,000
son qué?

424
00:14:29,000 --> 00:14:30,000
Pues dónde pones

425
00:14:30,000 --> 00:14:31,000
el ocho

426
00:14:34,000 --> 00:14:35,000
y dónde pones

427
00:14:35,000 --> 00:14:36,000
el dos

428
00:14:37,000 --> 00:14:38,000
y el tres

429
00:14:38,000 --> 00:14:39,000
y el cuatro

430
00:14:39,000 --> 00:14:40,000
y ahora transforma

431
00:14:40,000 --> 00:14:41,000
pon la coma

432
00:14:41,000 --> 00:14:42,000
donde te dé la gana

433
00:14:44,000 --> 00:14:45,000
¿Lo quieres

434
00:14:45,000 --> 00:14:46,000
en milímetros?

435
00:14:48,000 --> 00:14:49,000
Esto sería metro

436
00:14:49,000 --> 00:14:50,000
¿verdad?

437
00:14:50,000 --> 00:14:51,000
Sí

438
00:14:51,000 --> 00:14:52,000
Así que esto es metro

439
00:14:52,000 --> 00:14:53,000
esto es metro

440
00:14:53,000 --> 00:14:54,000
esto es metro

441
00:14:54,000 --> 00:14:55,000
esto es metro

442
00:14:55,000 --> 00:14:56,000
esto es metro

443
00:14:56,000 --> 00:14:57,000
esto es metro

444
00:14:57,000 --> 00:14:58,000
y esto es metro

445
00:14:59,000 --> 00:15:00,000
Si la quiero

446
00:15:00,000 --> 00:15:01,000
en milímetros

447
00:15:01,000 --> 00:15:02,000
¿Dónde pongo la coma?

448
00:15:06,000 --> 00:15:07,000
Pues que tendré

449
00:15:07,000 --> 00:15:08,000
que rellenar

450
00:15:09,000 --> 00:15:10,000
Pues mira

451
00:15:10,000 --> 00:15:12,000
328,4 metros

452
00:15:12,000 --> 00:15:15,000
son 328.400 milímetros

453
00:15:17,000 --> 00:15:18,000
Claro

454
00:15:18,000 --> 00:15:19,000
si me lo estás pidiendo

455
00:15:19,000 --> 00:15:20,000
en milímetros

456
00:15:20,000 --> 00:15:21,000
tendrás que tener

457
00:15:21,000 --> 00:15:22,000
la coma en milímetros

458
00:15:24,000 --> 00:15:25,000
No, es que no pongo coma

459
00:15:25,000 --> 00:15:26,000
por si no tengo

460
00:15:26,000 --> 00:15:27,000
nada detrás

461
00:15:27,000 --> 00:15:28,000
no pongo coma

462
00:15:29,000 --> 00:15:30,000
Claro

463
00:15:30,000 --> 00:15:31,000
pero vale

464
00:15:31,000 --> 00:15:32,000
dámelo en milímetros

465
00:15:34,000 --> 00:15:35,000
¿Dónde pongo la coma?

466
00:15:37,000 --> 00:15:38,000
Claro, aquí el problema

467
00:15:38,000 --> 00:15:39,000
que tengo

468
00:15:39,000 --> 00:15:40,000
si lo paso a milímetros

469
00:15:41,000 --> 00:15:42,000
es que yo tendría

470
00:15:42,000 --> 00:15:43,000
que poner

471
00:15:43,000 --> 00:15:44,000
cero

472
00:15:44,000 --> 00:15:45,000
porque no llego

473
00:15:45,000 --> 00:15:46,000
a tener una unidad

474
00:15:46,000 --> 00:15:47,000
y por eso tengo

475
00:15:47,000 --> 00:15:48,000
que poner el cero delante

476
00:15:48,000 --> 00:15:49,000
y estos ceros de aquí

477
00:15:49,000 --> 00:15:50,000
me los puedo ventilar

478
00:15:50,000 --> 00:15:51,000
y merendar

479
00:15:51,000 --> 00:15:53,000
porque no me aportan nada

480
00:15:54,000 --> 00:15:55,000
Entonces

481
00:15:55,000 --> 00:15:56,000
328,4 metros

482
00:15:58,000 --> 00:15:59,000
serían

483
00:15:59,000 --> 00:16:02,000
0,03284 milímetros

484
00:16:04,000 --> 00:16:05,000
Es difícil

485
00:16:06,000 --> 00:16:07,000
Solo tengo que saber

486
00:16:07,000 --> 00:16:08,000
lo que estoy leyendo

487
00:16:08,000 --> 00:16:09,000
y lo que estoy poniendo

488
00:16:09,000 --> 00:16:10,000
Y si yo te dijera

489
00:16:13,000 --> 00:16:14,000
que estos son

490
00:16:21,000 --> 00:16:22,000
dos

491
00:16:24,000 --> 00:16:25,000
decámetros

492
00:16:25,000 --> 00:16:26,000
porque esto es

493
00:16:26,000 --> 00:16:27,000
de K es de AM

494
00:16:27,000 --> 00:16:28,000
para no confundir

495
00:16:28,000 --> 00:16:29,000
con DC

496
00:16:29,000 --> 00:16:30,000
que es de F

497
00:16:30,000 --> 00:16:31,000
de M

498
00:16:31,000 --> 00:16:32,000
Dos decámetros

499
00:16:33,000 --> 00:16:34,000
y

500
00:16:35,000 --> 00:16:37,000
52 decímetros

501
00:16:39,000 --> 00:16:40,000
Y lo quiero

502
00:16:40,000 --> 00:16:41,000
pasar

503
00:16:41,000 --> 00:16:42,000
a

504
00:16:45,000 --> 00:16:46,000
hectómetros

505
00:16:58,000 --> 00:16:59,000
0,2

506
00:17:00,000 --> 00:17:01,000
Dos decámetros

507
00:17:01,000 --> 00:17:02,000
y 52 decímetros

508
00:17:02,000 --> 00:17:03,000
Voy a borrar

509
00:17:03,000 --> 00:17:04,000
todo esto

510
00:17:04,000 --> 00:17:05,000
que no me hace falta

511
00:17:07,000 --> 00:17:08,000
El dos en el decá

512
00:17:09,000 --> 00:17:10,000
El dos en el decá

513
00:17:10,000 --> 00:17:11,000
Vale

514
00:17:11,000 --> 00:17:12,000
Te lo compro

515
00:17:12,000 --> 00:17:13,000
Cero

516
00:17:13,000 --> 00:17:14,000
No

517
00:17:14,000 --> 00:17:15,000
Cinco, dos

518
00:17:15,000 --> 00:17:16,000
decímetros

519
00:17:16,000 --> 00:17:17,000
Entonces

520
00:17:17,000 --> 00:17:18,000
Vale

521
00:17:18,000 --> 00:17:19,000
En lugar de un cinco

522
00:17:19,000 --> 00:17:20,000
En lugar de cincuenta y dos

523
00:17:20,000 --> 00:17:21,000
voy a ponerte

524
00:17:21,000 --> 00:17:22,000
un seis

525
00:17:22,000 --> 00:17:23,000
para que no se confundan

526
00:17:23,000 --> 00:17:24,000
las cifras

527
00:17:24,000 --> 00:17:25,000
y no se repitan

528
00:17:25,000 --> 00:17:26,000
Entonces

529
00:17:26,000 --> 00:17:27,000
¿Y dónde lo pongo?

530
00:17:27,000 --> 00:17:28,000
En DC

531
00:17:29,000 --> 00:17:30,000
Es otra cantidad

532
00:17:30,000 --> 00:17:31,000
así que la pongo debajo

533
00:17:31,000 --> 00:17:32,000
Y

534
00:17:32,000 --> 00:17:33,000
entonces el cinco

535
00:17:34,000 --> 00:17:35,000
Vale

536
00:17:36,000 --> 00:17:37,000
¿Cuánto te da esto?

537
00:17:41,000 --> 00:17:42,000
Entonces

538
00:17:42,000 --> 00:17:43,000
Claro

539
00:17:43,000 --> 00:17:44,000
Entonces hectómetros sería

540
00:17:46,000 --> 00:17:47,000
Si yo lo sumo

541
00:17:48,000 --> 00:17:49,000
me quedaría

542
00:17:49,000 --> 00:17:52,000
0,256 hectómetros

543
00:17:54,000 --> 00:17:55,000
Esta medida

544
00:17:55,000 --> 00:17:56,000
dice que está dada

545
00:17:56,000 --> 00:17:57,000
en forma compleja

546
00:17:57,000 --> 00:17:58,000
¿Por qué?

547
00:18:00,000 --> 00:18:01,000
Porque te está dando

548
00:18:02,000 --> 00:18:03,000
una y otra

549
00:18:03,000 --> 00:18:04,000
Te está dando varias unidades

550
00:18:04,000 --> 00:18:05,000
Claro

551
00:18:05,000 --> 00:18:06,000
Ahí está

552
00:18:06,000 --> 00:18:07,000
Te está dando varias unidades

553
00:18:07,000 --> 00:18:08,000
de medida

554
00:18:08,000 --> 00:18:09,000
Entonces por eso dice

555
00:18:09,000 --> 00:18:10,000
que está en forma compleja

556
00:18:10,000 --> 00:18:11,000
Y yo normalmente

557
00:18:11,000 --> 00:18:12,000
te lo voy a devolver solo

558
00:18:12,000 --> 00:18:13,000
en forma incompleja

559
00:18:13,000 --> 00:18:14,000
con una sola unidad

560
00:18:14,000 --> 00:18:15,000
de medida

561
00:18:15,000 --> 00:18:16,000
¿De acuerdo?

562
00:18:16,000 --> 00:18:17,000
Y si yo te dijera

563
00:18:18,000 --> 00:18:19,000
Vamos a borrar esto

564
00:18:23,000 --> 00:18:24,000
Que son

565
00:18:24,000 --> 00:18:25,000
al revés

566
00:18:29,000 --> 00:18:31,000
Dos decímetros

567
00:18:32,000 --> 00:18:33,000
y

568
00:18:33,000 --> 00:18:35,000
cincuenta y seis metros

569
00:18:35,000 --> 00:18:37,000
¿Cuántos hectómetros son?

570
00:18:42,000 --> 00:18:43,000
Entonces

571
00:18:44,000 --> 00:18:45,000
El dos en deci

572
00:18:45,000 --> 00:18:46,000
Muy bien

573
00:18:50,000 --> 00:18:51,000
El seis en el metro

574
00:18:51,000 --> 00:18:52,000
Ah

575
00:18:52,000 --> 00:18:53,000
Espera

576
00:18:53,000 --> 00:18:54,000
Vamos a cambiarlo

577
00:18:54,000 --> 00:18:55,000
Que sean unidades

578
00:18:55,000 --> 00:18:56,000
Que sean metros

579
00:18:58,000 --> 00:18:59,000
Que sean

580
00:19:01,000 --> 00:19:02,000
Centímetros

581
00:19:02,000 --> 00:19:03,000
Perdón

582
00:19:03,000 --> 00:19:04,000
Vamos a poner centímetro

583
00:19:04,000 --> 00:19:05,000
que si no no va a salir

584
00:19:05,000 --> 00:19:06,000
lo que quiero hacer

585
00:19:06,000 --> 00:19:07,000
Centímetros

586
00:19:09,000 --> 00:19:10,000
¿El seis en?

587
00:19:12,000 --> 00:19:13,000
¿El seis dónde?

588
00:19:13,000 --> 00:19:14,000
En el centímetro

589
00:19:14,000 --> 00:19:15,000
¿Y qué me pasa?

590
00:19:16,000 --> 00:19:17,000
Vale

591
00:19:17,000 --> 00:19:18,000
No pasa nada

592
00:19:19,000 --> 00:19:20,000
Y sumas

593
00:19:22,000 --> 00:19:23,000
Si tienes dos decímetros

594
00:19:23,000 --> 00:19:24,000
por un lado

595
00:19:24,000 --> 00:19:25,000
y cinco decímetros

596
00:19:25,000 --> 00:19:26,000
por otro

597
00:19:26,000 --> 00:19:27,000
¿En total qué tendrás?

598
00:19:29,000 --> 00:19:30,000
Setenta y seis

599
00:19:30,000 --> 00:19:31,000
¿Setenta y seis qué?

600
00:19:33,000 --> 00:19:34,000
¿Setenta y seis qué?

601
00:19:35,000 --> 00:19:36,000
Milímetros

602
00:19:36,000 --> 00:19:37,000
No

603
00:19:37,000 --> 00:19:38,000
No, de centímetros

604
00:19:38,000 --> 00:19:39,000
Centímetros

605
00:19:39,000 --> 00:19:40,000
Muy bien

606
00:19:40,000 --> 00:19:41,000
Porque el seis está

607
00:19:41,000 --> 00:19:42,000
en los centímetros

608
00:19:42,000 --> 00:19:43,000
Pero yo no quiero

609
00:19:43,000 --> 00:19:44,000
setenta y seis centímetros

610
00:19:44,000 --> 00:19:45,000
¿Qué quiero?

611
00:19:45,000 --> 00:19:46,000
En hectómetros

612
00:19:46,000 --> 00:19:47,000
Pues entonces

613
00:19:47,000 --> 00:19:48,000
Sería cero

614
00:19:48,000 --> 00:19:49,000
acá en hectómetros

615
00:19:49,000 --> 00:19:50,000
coma

616
00:19:51,000 --> 00:19:52,000
Entonces fíjate

617
00:19:52,000 --> 00:19:53,000
que para pasar

618
00:19:53,000 --> 00:19:54,000
de los centímetros

619
00:19:54,000 --> 00:19:55,000
a los hectómetros

620
00:19:55,000 --> 00:19:56,000
tengo que dividir

621
00:19:56,000 --> 00:19:57,000
porque voy a una unidad

622
00:19:57,000 --> 00:19:58,000
más grande

623
00:19:58,000 --> 00:19:59,000
Entonces tengo que dividir

624
00:19:59,000 --> 00:20:00,000
entre cuántos ceros

625
00:20:00,000 --> 00:20:01,000
tantos lugares

626
00:20:01,000 --> 00:20:02,000
como tenga

627
00:20:02,000 --> 00:20:03,000
Entonces aquí tengo

628
00:20:03,000 --> 00:20:04,000
de centímetro a hectómetro

629
00:20:04,000 --> 00:20:06,000
uno, dos, tres, cuatro

630
00:20:06,000 --> 00:20:07,000
cuatro lugares

631
00:20:07,000 --> 00:20:08,000
corro a la coma

632
00:20:08,000 --> 00:20:09,000
cuatro lugares a la izquierda

633
00:20:11,000 --> 00:20:12,000
Si voy de una unidad

634
00:20:12,000 --> 00:20:13,000
pequeña a una grande

635
00:20:13,000 --> 00:20:14,000
tengo que dividir

636
00:20:15,000 --> 00:20:16,000
porque tengo que correr

637
00:20:16,000 --> 00:20:17,000
la coma a la izquierda

638
00:20:17,000 --> 00:20:18,000
Si voy de una grande

639
00:20:18,000 --> 00:20:19,000
a una pequeña

640
00:20:19,000 --> 00:20:20,000
tengo que multiplicar

641
00:20:20,000 --> 00:20:21,000
porque en hectómetros

642
00:20:21,000 --> 00:20:22,000
son muchos centímetros

643
00:20:22,000 --> 00:20:23,000
son diez mil

644
00:20:23,000 --> 00:20:24,000
Entonces multiplico

645
00:20:24,000 --> 00:20:25,000
corriendo la coma

646
00:20:25,000 --> 00:20:26,000
a la derecha

647
00:20:27,000 --> 00:20:28,000
Hasta que llegues

648
00:20:28,000 --> 00:20:29,000
Hasta que llegues

649
00:20:29,000 --> 00:20:30,000
Entonces lo que es interesante

650
00:20:30,000 --> 00:20:32,000
es saberte el orden

651
00:20:32,000 --> 00:20:33,000
porque entonces simplemente

652
00:20:33,000 --> 00:20:34,000
con saberte el orden

653
00:20:34,000 --> 00:20:35,000
haces el cambio

654
00:20:36,000 --> 00:20:37,000
Vale

655
00:20:37,000 --> 00:20:38,000
A partir del metro

656
00:20:39,000 --> 00:20:40,000
se coge un cubo

657
00:20:47,000 --> 00:20:48,000
¿Qué tiene?

658
00:20:49,000 --> 00:20:50,000
Un decímetro

659
00:20:51,000 --> 00:20:52,000
No, perdón

660
00:20:52,000 --> 00:20:53,000
Vamos primero con el cuadrado

661
00:20:54,000 --> 00:20:55,000
Vamos a ir primero

662
00:20:55,000 --> 00:20:56,000
con el cuadrado

663
00:20:56,000 --> 00:20:57,000
¿Qué me pasa?

664
00:20:57,000 --> 00:20:58,000
Si yo lo que quiero

665
00:20:58,000 --> 00:20:59,000
es una unidad de superficie

666
00:21:00,000 --> 00:21:01,000
Yo tengo que coger

667
00:21:02,000 --> 00:21:03,000
una unidad

668
00:21:03,000 --> 00:21:04,000
más o menos

669
00:21:04,000 --> 00:21:05,000
regular

670
00:21:05,000 --> 00:21:06,000
o rectángulos

671
00:21:06,000 --> 00:21:07,000
¿Con triángulos

672
00:21:07,000 --> 00:21:08,000
podría medir bien?

673
00:21:08,000 --> 00:21:09,000
No

674
00:21:09,000 --> 00:21:10,000
¿Entonces qué se coge?

675
00:21:10,000 --> 00:21:11,000
¿Con círculos

676
00:21:11,000 --> 00:21:12,000
puedo medir bien?

677
00:21:12,000 --> 00:21:13,000
No, que dejan huequitos

678
00:21:13,000 --> 00:21:15,000
Así que cojo un cuadrado

679
00:21:15,000 --> 00:21:16,000
porque los puedo superponer bien

680
00:21:16,000 --> 00:21:18,000
y mire lo mismo de lado

681
00:21:18,000 --> 00:21:19,000
Entonces

682
00:21:19,000 --> 00:21:20,000
me cabe de la misma manera

683
00:21:20,000 --> 00:21:21,000
por un lado que por otro

684
00:21:22,000 --> 00:21:23,000
Por eso se utilizan

685
00:21:23,000 --> 00:21:24,000
medidas cuadradas

686
00:21:25,000 --> 00:21:27,000
Porque utilizo un cuadrado

687
00:21:27,000 --> 00:21:28,000
Entonces

688
00:21:28,000 --> 00:21:29,000
lo que yo hago es que

689
00:21:29,000 --> 00:21:30,000
cojo un cuadrado

690
00:21:32,000 --> 00:21:33,000
de unidad

691
00:21:34,000 --> 00:21:35,000
Esa es mi unidad

692
00:21:35,000 --> 00:21:36,000
mi patrón

693
00:21:36,000 --> 00:21:37,000
Cojo un cuadrado

694
00:21:37,000 --> 00:21:38,000
de patrón

695
00:21:38,000 --> 00:21:39,000
y miro a ver

696
00:21:39,000 --> 00:21:40,000
cuántas veces

697
00:21:40,000 --> 00:21:41,000
me cabe este cuadrado

698
00:21:41,000 --> 00:21:42,000
en la superficie

699
00:21:42,000 --> 00:21:43,000
Por ejemplo

700
00:21:43,000 --> 00:21:44,000
aquí

701
00:21:44,000 --> 00:21:45,000
baldosas

702
00:21:45,000 --> 00:21:46,000
La baldosa son cuadradas

703
00:21:47,000 --> 00:21:48,000
Es mi unidad

704
00:21:48,000 --> 00:21:49,000
una baldosa

705
00:21:49,000 --> 00:21:50,000
¿Cuántas baldosas

706
00:21:50,000 --> 00:21:51,000
mide esta superficie

707
00:21:52,000 --> 00:21:53,000
de clase?

708
00:21:54,000 --> 00:21:55,000
Ahora, levantarse y contar

709
00:21:58,000 --> 00:21:59,000
Que uno ponte a un lado

710
00:21:59,000 --> 00:22:00,000
que otro ponte al otro

711
00:22:10,000 --> 00:22:11,000
Hacérmelo bien

712
00:22:11,000 --> 00:22:12,000
porque esto no es entero

713
00:22:12,000 --> 00:22:13,000
ni de coña

714
00:22:14,000 --> 00:22:15,000
Y eso tampoco

715
00:22:25,000 --> 00:22:26,000
Pero esa no es entera

716
00:22:26,000 --> 00:22:27,000
Pero esa no es entera

717
00:22:27,000 --> 00:22:28,000
Entonces

718
00:22:28,000 --> 00:22:29,000
19,5

719
00:22:29,000 --> 00:22:30,000
Vale, 19,5

720
00:22:30,000 --> 00:22:31,000
Esta habitación

721
00:22:31,000 --> 00:22:32,000
nos mide de aquí

722
00:22:34,000 --> 00:22:35,000
19,5 baldosas

723
00:22:37,000 --> 00:22:38,000
cuadradas

724
00:22:38,000 --> 00:22:39,000
cuadradas

725
00:22:43,000 --> 00:22:44,000
13,5

726
00:22:44,000 --> 00:22:45,000
13

727
00:22:46,000 --> 00:22:47,000
Ya, 13,3

728
00:22:52,000 --> 00:22:53,000
Vale, venga

729
00:22:53,000 --> 00:22:54,000
13,5

730
00:22:54,000 --> 00:22:55,000
Vamos a poner 13,4

731
00:22:56,000 --> 00:22:57,000
Estos son

732
00:22:58,000 --> 00:22:59,000
De aquí de longitud

733
00:22:59,000 --> 00:23:00,000
13,5

734
00:23:01,000 --> 00:23:02,000
lo que mide la baldosa

735
00:23:02,000 --> 00:23:03,000
Y de aquí de longitud

736
00:23:03,000 --> 00:23:04,000
13,4

737
00:23:04,000 --> 00:23:05,000
lo que mide la baldosa

738
00:23:06,000 --> 00:23:07,000
Entonces

739
00:23:07,000 --> 00:23:08,000
Yo quiero saber

740
00:23:08,000 --> 00:23:09,000
¿Cuántas tengo en total?

741
00:23:09,000 --> 00:23:10,000
¿Cómo lo hago?

742
00:23:11,000 --> 00:23:12,000
¿Cómo hacíamos esto?

743
00:23:13,000 --> 00:23:14,000
Para saber

744
00:23:14,000 --> 00:23:15,000
¿Cuántas baldosas

745
00:23:15,000 --> 00:23:16,000
en total tenías?

746
00:23:17,000 --> 00:23:18,000
Si tengo 5 en un lado

747
00:23:18,000 --> 00:23:19,000
y 4 en el otro

748
00:23:19,000 --> 00:23:20,000
5 por 4, ¿no?

749
00:23:20,000 --> 00:23:21,000
5 veces 4

750
00:23:21,000 --> 00:23:22,000
Pues si tengo

751
00:23:22,000 --> 00:23:23,000
13,4

752
00:23:23,000 --> 00:23:24,000
y 19,5

753
00:23:26,000 --> 00:23:27,000
Claro

754
00:23:37,000 --> 00:23:38,000
Vale

755
00:23:55,000 --> 00:23:56,000
Baldosas cuadradas

756
00:23:58,000 --> 00:23:59,000
¿Lo veis?

757
00:24:00,000 --> 00:24:01,000
Y eso solo lo puedo hacer

758
00:24:01,000 --> 00:24:02,000
porque

759
00:24:02,000 --> 00:24:03,000
esto y esto

760
00:24:03,000 --> 00:24:04,000
es igual

761
00:24:04,000 --> 00:24:05,000
Entonces

762
00:24:05,000 --> 00:24:06,000
¿Qué pasa?

763
00:24:06,000 --> 00:24:07,000
En un sistema métrico decimal

764
00:24:07,000 --> 00:24:08,000
no voy a coger

765
00:24:08,000 --> 00:24:09,000
la unidad de la baldosa

766
00:24:10,000 --> 00:24:11,000
¿Qué unidad voy a coger?

767
00:24:13,000 --> 00:24:14,000
¿En qué se basa

768
00:24:14,000 --> 00:24:15,000
tu sistema métrico?

769
00:24:17,000 --> 00:24:18,000
El primero que coges

770
00:24:22,000 --> 00:24:23,000
¿Cuál es la primera unidad

771
00:24:23,000 --> 00:24:24,000
que hemos definido?

772
00:24:25,000 --> 00:24:26,000
El metro

773
00:24:26,000 --> 00:24:27,000
Pues ¿Qué unidad de longitud

774
00:24:27,000 --> 00:24:28,000
voy a coger?

775
00:24:28,000 --> 00:24:29,000
¿El lado de la baldosa

776
00:24:29,000 --> 00:24:30,000
o un metro?

777
00:24:31,000 --> 00:24:32,000
Un metro

778
00:24:34,000 --> 00:24:35,000
Entonces

779
00:24:35,000 --> 00:24:36,000
lo que se hace

780
00:24:36,000 --> 00:24:37,000
es coger

781
00:24:37,000 --> 00:24:38,000
una baldosa

782
00:24:39,000 --> 00:24:40,000
que aquí mide

783
00:24:40,000 --> 00:24:41,000
un metro

784
00:24:41,000 --> 00:24:42,000
y aquí mide

785
00:24:42,000 --> 00:24:43,000
un metro

786
00:24:43,000 --> 00:24:44,000
Pero esta no es

787
00:24:44,000 --> 00:24:45,000
mi unidad de superficie

788
00:24:45,000 --> 00:24:46,000
Esta es la unidad

789
00:24:46,000 --> 00:24:47,000
de longitud

790
00:24:47,000 --> 00:24:48,000
¿Cuál es la unidad

791
00:24:48,000 --> 00:24:49,000
de superficie?

792
00:24:49,000 --> 00:24:50,000
Esto

793
00:24:52,000 --> 00:24:53,000
¿Y cómo la llamo?

794
00:25:00,000 --> 00:25:01,000
Pues si el otro

795
00:25:01,000 --> 00:25:02,000
era una baldosa cuadrada

796
00:25:02,000 --> 00:25:03,000
un metro cuadrado

797
00:25:04,000 --> 00:25:05,000
Un cuadrado

798
00:25:05,000 --> 00:25:06,000
de un metro de lado

799
00:25:08,000 --> 00:25:09,000
¿Eso lo vemos?

800
00:25:10,000 --> 00:25:11,000
¡Ojo!

801
00:25:11,000 --> 00:25:12,000
Que aunque tengan

802
00:25:12,000 --> 00:25:13,000
nombres parecidos

803
00:25:13,000 --> 00:25:14,000
se distinguen

804
00:25:14,000 --> 00:25:15,000
como unidades de medida

805
00:25:15,000 --> 00:25:16,000
tanto como el litro

806
00:25:16,000 --> 00:25:17,000
y el metro

807
00:25:18,000 --> 00:25:19,000
A que el litro y el metro

808
00:25:19,000 --> 00:25:20,000
entendéis muy bien

809
00:25:20,000 --> 00:25:21,000
que miden cosas diferentes

810
00:25:21,000 --> 00:25:22,000
Pues el metro cuadrado

811
00:25:22,000 --> 00:25:23,000
y el metro

812
00:25:23,000 --> 00:25:24,000
miden cosas diferentes

813
00:25:24,000 --> 00:25:25,000
Porque uno mide

814
00:25:25,000 --> 00:25:26,000
una longitud

815
00:25:26,000 --> 00:25:27,000
que es solo

816
00:25:27,000 --> 00:25:28,000
lo largo de una cuerda

817
00:25:28,000 --> 00:25:29,000
y otro está midiendo

818
00:25:29,000 --> 00:25:30,000
una superficie

819
00:25:30,000 --> 00:25:31,000
que es un plano

820
00:25:31,000 --> 00:25:32,000
No miden cosas iguales

821
00:25:32,000 --> 00:25:33,000
Cosas que suenan

822
00:25:33,000 --> 00:25:34,000
parecido porque

823
00:25:34,000 --> 00:25:35,000
para medir superficies

824
00:25:35,000 --> 00:25:36,000
me baso en la medida

825
00:25:36,000 --> 00:25:37,000
de longitud

826
00:25:37,000 --> 00:25:38,000
básica

827
00:25:38,000 --> 00:25:39,000
que he cogido

828
00:25:39,000 --> 00:25:40,000
que es el metro

829
00:25:41,000 --> 00:25:42,000
Y construyo la baldosa

830
00:25:42,000 --> 00:25:43,000
a través de

831
00:25:43,000 --> 00:25:44,000
un metro con un metro

832
00:25:45,000 --> 00:25:46,000
Pero mi unidad

833
00:25:46,000 --> 00:25:47,000
de superficie

834
00:25:47,000 --> 00:25:48,000
es el metro cuadrado

835
00:25:48,000 --> 00:25:49,000
¿Y qué me pasa

836
00:25:49,000 --> 00:25:50,000
si yo ahora

837
00:25:50,000 --> 00:25:51,000
quiero las equivalencias?

838
00:25:53,000 --> 00:25:54,000
Pues vamos a ver

839
00:25:55,000 --> 00:25:56,000
Yo no quiero

840
00:25:56,000 --> 00:25:57,000
ahora medir

841
00:25:57,000 --> 00:25:58,000
en metros cuadrados

842
00:25:58,000 --> 00:25:59,000
Quiero medir en algo

843
00:25:59,000 --> 00:26:00,000
que sea

844
00:26:00,000 --> 00:26:01,000
un decímetro

845
00:26:01,000 --> 00:26:02,000
un decímetro cuadrado

846
00:26:03,000 --> 00:26:04,000
que será

847
00:26:04,000 --> 00:26:05,000
un decímetro

848
00:26:05,000 --> 00:26:06,000
por un decímetro

849
00:26:06,000 --> 00:26:07,000
que es

850
00:26:08,000 --> 00:26:09,000
esto de aquí

851
00:26:10,000 --> 00:26:11,000
Quiero saber

852
00:26:11,000 --> 00:26:12,000
cuántos cuadraditos

853
00:26:12,000 --> 00:26:13,000
Voy a ponerlo

854
00:26:13,000 --> 00:26:14,000
de color verde

855
00:26:16,000 --> 00:26:17,000
Quiero saber

856
00:26:17,000 --> 00:26:18,000
cuántos cuadraditos

857
00:26:18,000 --> 00:26:19,000
verdes

858
00:26:19,000 --> 00:26:20,000
equivalen a un azul

859
00:26:22,000 --> 00:26:23,000
¿Cómo lo podría averiguar?

860
00:26:24,000 --> 00:26:25,000
¿Por qué?

861
00:26:31,000 --> 00:26:32,000
No, no

862
00:26:32,000 --> 00:26:33,000
Pero déjate de la memoria

863
00:26:33,000 --> 00:26:34,000
y razona con lo que

864
00:26:34,000 --> 00:26:35,000
te estoy dando

865
00:26:35,000 --> 00:26:36,000
Con lo que tienes

866
00:26:36,000 --> 00:26:37,000
en la pizarra

867
00:26:37,000 --> 00:26:38,000
¿Qué ves?

868
00:26:39,000 --> 00:26:40,000
Tú no ves

869
00:26:40,000 --> 00:26:41,000
la equivalencia

870
00:26:41,000 --> 00:26:42,000
entre un metro cuadrado

871
00:26:42,000 --> 00:26:43,000
y un decímetro cuadrado

872
00:26:43,000 --> 00:26:44,000
porque esa no la sabes

873
00:26:44,000 --> 00:26:45,000
Es la que estamos buscando

874
00:26:45,000 --> 00:26:46,000
Pero tú sí que ves

875
00:26:47,000 --> 00:26:48,000
¿Qué ves?

876
00:26:51,000 --> 00:26:52,000
Sí

877
00:26:52,000 --> 00:26:53,000
¿Ya están relacionadas?

878
00:26:55,000 --> 00:26:56,000
Sí

879
00:26:56,000 --> 00:26:57,000
¿Cómo?

880
00:26:58,000 --> 00:26:59,000
¿La longitud?

881
00:26:59,000 --> 00:27:00,000
¿Cómo?

882
00:27:01,000 --> 00:27:03,000
¿Qué relación de longitud tienen?

883
00:27:04,000 --> 00:27:05,000
¿Un metro?

884
00:27:06,000 --> 00:27:07,000
¿Un metro cuánto es?

885
00:27:08,000 --> 00:27:09,000
Diez

886
00:27:09,000 --> 00:27:10,000
¿Diez qué?

887
00:27:10,000 --> 00:27:11,000
Metros

888
00:27:11,000 --> 00:27:12,000
Ah, diez

889
00:27:16,000 --> 00:27:17,000
Ah, diez unidades

890
00:27:17,000 --> 00:27:18,000
¿Diez qué?

891
00:27:19,000 --> 00:27:20,000
De decímetros

892
00:27:20,000 --> 00:27:21,000
Claro

893
00:27:21,000 --> 00:27:22,000
Entonces dices

894
00:27:22,000 --> 00:27:23,000
Bueno, yo no puedo relacionar

895
00:27:23,000 --> 00:27:24,000
el cuadradito todavía

896
00:27:25,000 --> 00:27:26,000
Pero como me has dado un metro

897
00:27:26,000 --> 00:27:27,000
y tú quieres el decímetro

898
00:27:27,000 --> 00:27:28,000
Yo el metro y el decímetro

899
00:27:28,000 --> 00:27:29,000
que son unidades de longitud

900
00:27:30,000 --> 00:27:31,000
Sí las sé relacionar

901
00:27:32,000 --> 00:27:33,000
Y yo sé que un metro

902
00:27:33,000 --> 00:27:34,000
son cuántas unidades de longitud

903
00:27:35,000 --> 00:27:36,000
Diez

904
00:27:36,000 --> 00:27:37,000
Diez decímetros

905
00:27:38,000 --> 00:27:39,000
Así que esto lo parto

906
00:27:41,000 --> 00:27:42,000
En diez

907
00:27:43,000 --> 00:27:44,000
Y cada una de ellas

908
00:27:44,000 --> 00:27:45,000
es un decímetro

909
00:27:45,000 --> 00:27:46,000
Y el otro metro, por tanto

910
00:27:51,000 --> 00:27:52,000
En diez

911
00:27:53,000 --> 00:27:54,000
Y entonces puedo saber

912
00:27:54,000 --> 00:27:55,000
cuántas baldosas tengo

913
00:27:55,000 --> 00:27:56,000
en total

914
00:27:57,000 --> 00:27:58,000
¿Cuántas?

915
00:27:58,000 --> 00:27:59,000
Cien

916
00:27:59,000 --> 00:28:00,000
Cien, diez por el diez

917
00:28:01,000 --> 00:28:02,000
Así que resulta

918
00:28:02,000 --> 00:28:03,000
que este cuadrado

919
00:28:04,000 --> 00:28:05,000
en total

920
00:28:05,000 --> 00:28:06,000
son cien

921
00:28:07,000 --> 00:28:08,000
decímetros cuadraditos

922
00:28:08,000 --> 00:28:09,000
como eso

923
00:28:10,000 --> 00:28:11,000
Así que

924
00:28:11,000 --> 00:28:12,000
¡Ojo!

925
00:28:12,000 --> 00:28:13,000
Porque para pasar

926
00:28:13,000 --> 00:28:14,000
del decímetro cuadrado

927
00:28:14,000 --> 00:28:15,000
al metro cuadrado

928
00:28:15,000 --> 00:28:16,000
tengo que dividir

929
00:28:16,000 --> 00:28:17,000
entre cien

930
00:28:17,000 --> 00:28:18,000
no entre diez

931
00:28:18,000 --> 00:28:19,000
Y para pasar

932
00:28:19,000 --> 00:28:20,000
del metro cuadrado

933
00:28:20,000 --> 00:28:21,000
al decímetro cuadrado

934
00:28:21,000 --> 00:28:22,000
tengo que multiplicar

935
00:28:22,000 --> 00:28:23,000
por cien

936
00:28:23,000 --> 00:28:24,000
no entre diez

937
00:28:24,000 --> 00:28:25,000
No por diez

938
00:28:25,000 --> 00:28:26,000
Entonces fíjate cómo queda

939
00:28:26,000 --> 00:28:28,000
porque yo tenía esta tabla

940
00:28:31,000 --> 00:28:32,000
Voy a cogerla

941
00:28:46,000 --> 00:28:47,000
Y la voy a pasar aquí

942
00:28:55,000 --> 00:28:56,000
¿Qué me pasa ahora?

943
00:29:12,000 --> 00:29:13,000
Que ahora

944
00:29:13,000 --> 00:29:14,000
todas estas

945
00:29:14,000 --> 00:29:15,000
para empezar

946
00:29:15,000 --> 00:29:16,000
la unidad

947
00:29:16,000 --> 00:29:17,000
la unidad

948
00:29:17,000 --> 00:29:18,000
perdón

949
00:29:18,000 --> 00:29:19,000
la unidad va a ser

950
00:29:19,000 --> 00:29:20,000
el metro cuadrado

951
00:29:22,000 --> 00:29:23,000
Porque estamos

952
00:29:23,000 --> 00:29:24,000
porque estamos hablando

953
00:29:24,000 --> 00:29:25,000
de superficie

954
00:29:26,000 --> 00:29:27,000
Y cada una

955
00:29:27,000 --> 00:29:28,000
de estas barras

956
00:29:28,000 --> 00:29:29,000
no es una sola

957
00:29:29,000 --> 00:29:30,000
sino que está dividida

958
00:29:32,000 --> 00:29:33,000
en dos

959
00:29:36,000 --> 00:29:37,000
Esperad, voy a hacer

960
00:29:37,000 --> 00:29:38,000
de otro color

961
00:29:38,000 --> 00:29:39,000
para que no las mezcléis

962
00:29:51,000 --> 00:29:52,000
¿Vale?

963
00:29:52,000 --> 00:29:53,000
Entonces

964
00:29:53,000 --> 00:29:54,000
yo voy a empezar contando

965
00:29:54,000 --> 00:29:55,000
decímetros cuadrados

966
00:29:55,000 --> 00:29:56,000
pequeñitos

967
00:29:58,000 --> 00:29:59,000
Voy a contar

968
00:29:59,000 --> 00:30:00,000
como estoy en decímetro cuadrado

969
00:30:00,000 --> 00:30:01,000
está aquí

970
00:30:01,000 --> 00:30:02,000
un decímetro cuadrado

971
00:30:02,000 --> 00:30:03,000
que sería justo

972
00:30:04,000 --> 00:30:05,000
un cuadradito

973
00:30:05,000 --> 00:30:06,000
como este

974
00:30:06,000 --> 00:30:07,000
¿Le puedo añadir otro?

975
00:30:09,000 --> 00:30:10,000
Sí, ¿verdad?

976
00:30:10,000 --> 00:30:11,000
Tendría dos y otro

977
00:30:11,000 --> 00:30:12,000
y tendría tres

978
00:30:13,000 --> 00:30:14,000
Entonces

979
00:30:14,000 --> 00:30:15,000
yo voy subiendo aquí

980
00:30:15,000 --> 00:30:16,000
uno

981
00:30:17,000 --> 00:30:18,000
dos

982
00:30:18,000 --> 00:30:19,000
treinta y dos

983
00:30:20,000 --> 00:30:21,000
cincuenta y dos

984
00:30:23,000 --> 00:30:24,000
ochenta y ocho

985
00:30:24,000 --> 00:30:25,000
decímetros cuadrados

986
00:30:29,000 --> 00:30:30,000
noventa y ocho

987
00:30:30,000 --> 00:30:31,000
decímetros cuadrados

988
00:30:35,000 --> 00:30:36,000
noventa y nueve

989
00:30:36,000 --> 00:30:37,000
decímetros cuadrados

990
00:30:38,000 --> 00:30:39,000
pero hasta que

991
00:30:39,000 --> 00:30:40,000
no le sume uno más

992
00:30:41,000 --> 00:30:42,000
y tenga

993
00:30:42,000 --> 00:30:43,000
cien decímetros cuadrados

994
00:30:44,000 --> 00:30:45,000
no voy a tener un metro

995
00:30:46,000 --> 00:30:47,000
cuadrado

996
00:30:48,000 --> 00:30:49,000
¿Lo entendemos?

997
00:30:49,000 --> 00:30:50,000
Por eso va partido en dos

998
00:30:51,000 --> 00:30:52,000
Entonces, ojo

999
00:30:52,000 --> 00:30:53,000
porque aquí ya

1000
00:30:53,000 --> 00:30:54,000
la cosa cambia

1001
00:30:54,000 --> 00:30:55,000
Si yo te digo

1002
00:30:55,000 --> 00:30:56,000
que tengo

1003
00:30:56,000 --> 00:30:58,000
trescientos veintiocho coma cuatro

1004
00:30:58,000 --> 00:30:59,000
decímetros cuadrados

1005
00:31:00,000 --> 00:31:01,000
¿Qué te estoy diciendo?

1006
00:31:02,000 --> 00:31:03,000
Que no

1007
00:31:03,000 --> 00:31:04,000
que no

1008
00:31:04,000 --> 00:31:05,000
que no

1009
00:31:05,000 --> 00:31:06,000
que no

1010
00:31:06,000 --> 00:31:07,000
que no

1011
00:31:07,000 --> 00:31:08,000
que no

1012
00:31:08,000 --> 00:31:09,000
que no

1013
00:31:09,000 --> 00:31:10,000
que no

1014
00:31:10,000 --> 00:31:11,000
que no

1015
00:31:11,000 --> 00:31:12,000
¿Qué te estoy diciendo

1016
00:31:12,000 --> 00:31:13,000
que tengo?

1017
00:31:19,000 --> 00:31:20,000
¿Dónde pongo el ocho?

1018
00:31:25,000 --> 00:31:26,000
Muy bien

1019
00:31:27,000 --> 00:31:28,000
¿Pero en la izquierda

1020
00:31:28,000 --> 00:31:29,000
o en la derecha?

1021
00:31:29,000 --> 00:31:30,000
En la derecha

1022
00:31:34,000 --> 00:31:35,000
ocho decímetros cuadrados

1023
00:31:36,000 --> 00:31:37,000
¿Y luego?

1024
00:31:39,000 --> 00:31:40,000
El cuatro a la derecha

1025
00:31:41,000 --> 00:31:44,000
va el dos, el tres

1026
00:31:46,000 --> 00:31:47,000
Entonces si lo quiero

1027
00:31:47,000 --> 00:31:49,000
en milímetros cuadrados

1028
00:31:49,000 --> 00:31:50,000
¿Qué sería?

1029
00:31:51,000 --> 00:31:52,000
¿Cuántos?

1030
00:31:53,000 --> 00:31:54,000
En este caso dos

1031
00:31:54,000 --> 00:31:55,000
No, tres

1032
00:31:59,000 --> 00:32:01,000
¿Por qué tengo que llegar hasta aquí?

1033
00:32:02,000 --> 00:32:04,000
Porque las únicas unidades que cuento

1034
00:32:04,000 --> 00:32:07,000
son esa, esta, esta, esta

1035
00:32:08,000 --> 00:32:09,000
cada dos

1036
00:32:09,000 --> 00:32:10,000
¿Ha quedado claro?

1037
00:32:12,000 --> 00:32:13,000
Entonces

1038
00:32:13,000 --> 00:32:14,000
lo que hago

1039
00:32:14,000 --> 00:32:16,000
es como antes

1040
00:32:16,000 --> 00:32:17,000
cuento los lugares

1041
00:32:17,000 --> 00:32:19,000
digo, bueno, yo sé que voy a unidad

1042
00:32:19,000 --> 00:32:20,000
a una unidad más pequeña

1043
00:32:20,000 --> 00:32:21,000
de decímetro

1044
00:32:21,000 --> 00:32:23,000
la quiero en milímetros, ¿no?

1045
00:32:25,000 --> 00:32:27,000
Milímetros cuadrados

1046
00:32:27,000 --> 00:32:29,000
al ser más pequeña voy a multiplicar

1047
00:32:29,000 --> 00:32:32,000
¿De decí a milí cuántos lugares valen?

1048
00:32:33,000 --> 00:32:34,000
Dos

1049
00:32:34,000 --> 00:32:35,000
Pero cada uno de ellos

1050
00:32:35,000 --> 00:32:36,000
como estoy al cuadrado

1051
00:32:36,000 --> 00:32:37,000
¿Cuántos ceros son?

1052
00:32:39,000 --> 00:32:40,000
Dos por dos

1053
00:32:40,000 --> 00:32:41,000
que son cuatro

1054
00:32:41,000 --> 00:32:42,000
Es decir

1055
00:32:42,000 --> 00:32:44,000
voy a multiplicar por cuatro

1056
00:32:44,000 --> 00:32:46,000
si tenía la coma aquí

1057
00:32:47,000 --> 00:32:48,000
ahora escribiré

1058
00:32:48,000 --> 00:32:49,000
la coma

1059
00:32:49,000 --> 00:32:51,000
cuatro lugares más allá

1060
00:32:53,000 --> 00:32:54,000
pasando de aquí

1061
00:32:54,000 --> 00:32:55,000
aquí

1062
00:32:55,000 --> 00:32:56,000
¿Lo hemos entendido?

1063
00:32:57,000 --> 00:32:58,000
Y lo mismo para dividir

1064
00:32:58,000 --> 00:32:59,000
¿Y qué me pasará

1065
00:32:59,000 --> 00:33:01,000
con las unidades de volumen?

1066
00:33:03,000 --> 00:33:05,000
Necesito cubitos, ¿no?

1067
00:33:05,000 --> 00:33:07,000
Para medir volúmenes

1068
00:33:07,000 --> 00:33:08,000
si para medir el plano

1069
00:33:08,000 --> 00:33:09,000
necesito un cuadrado

1070
00:33:09,000 --> 00:33:10,000
para medir un volumen

1071
00:33:10,000 --> 00:33:11,000
necesito un cubito

1072
00:33:11,000 --> 00:33:12,000
de lado

1073
00:33:12,000 --> 00:33:13,000
un metro

1074
00:33:13,000 --> 00:33:14,000
entonces

1075
00:33:14,000 --> 00:33:15,000
para medir volúmenes

1076
00:33:15,000 --> 00:33:17,000
yo tengo cubitos

1077
00:33:17,000 --> 00:33:19,000
voy a hacer uno grande

1078
00:33:22,000 --> 00:33:23,000
en que esto vale

1079
00:33:23,000 --> 00:33:24,000
un metro

1080
00:33:26,000 --> 00:33:27,000
esto vale

1081
00:33:27,000 --> 00:33:28,000
un metro

1082
00:33:28,000 --> 00:33:29,000
y esto vale

1083
00:33:29,000 --> 00:33:30,000
un metro

1084
00:33:40,000 --> 00:33:41,000
Entonces, fíjate

1085
00:33:41,000 --> 00:33:43,000
yo aquí puedo hacer

1086
00:33:43,000 --> 00:33:45,000
el decímetro cúbico

1087
00:33:45,000 --> 00:33:47,000
o sea, el decímetro cuadrado

1088
00:33:47,000 --> 00:33:49,000
y lo tendré que elevar

1089
00:33:49,000 --> 00:33:50,000
un decímetro

1090
00:33:56,000 --> 00:33:58,000
para tener un decímetro cúbico

1091
00:33:59,000 --> 00:34:00,000
Entonces

1092
00:34:00,000 --> 00:34:01,000
¿Cómo hago el cambio?

1093
00:34:01,000 --> 00:34:04,000
Pues si el metro son diez decímetros

1094
00:34:04,000 --> 00:34:06,000
este metro son diez decímetros

1095
00:34:06,000 --> 00:34:09,000
y este metro son diez decímetros

1096
00:34:10,000 --> 00:34:11,000
en la plancha de abajo

1097
00:34:11,000 --> 00:34:12,000
me caberán

1098
00:34:13,000 --> 00:34:15,000
cien decímetros cuadrados

1099
00:34:15,000 --> 00:34:16,000
diez veces

1100
00:34:18,000 --> 00:34:19,000
por cien

1101
00:34:20,000 --> 00:34:21,000
mil

1102
00:34:23,000 --> 00:34:25,000
un metro cúbico

1103
00:34:25,000 --> 00:34:26,000
son mil

1104
00:34:28,000 --> 00:34:30,000
cien decímetros cuadrados

1105
00:34:30,000 --> 00:34:32,000
un metro cúbico

1106
00:34:32,000 --> 00:34:36,000
son mil decímetros cúbicos

1107
00:34:37,000 --> 00:34:39,000
necesito mil cubitos

1108
00:34:39,000 --> 00:34:40,000
de decímetro

1109
00:34:40,000 --> 00:34:42,000
de lado un decímetro

1110
00:34:42,000 --> 00:34:44,000
para cubrir

1111
00:34:44,000 --> 00:34:46,000
un cubo de lado un metro

1112
00:34:47,000 --> 00:34:49,000
Entonces, hago lo mismo

1113
00:34:49,000 --> 00:34:51,000
si yo quiero ahora pasar

1114
00:34:51,000 --> 00:34:53,000
ochocientos veintitrés

1115
00:34:53,000 --> 00:34:55,000
coma cuatro

1116
00:34:55,000 --> 00:34:56,000
cuarenta y dos

1117
00:34:56,000 --> 00:34:58,000
cuatrocientos veinticinco

1118
00:35:01,000 --> 00:35:04,000
decámetros cúbicos

1119
00:35:07,000 --> 00:35:10,000
lo quiero en hectómetros cúbicos

1120
00:35:13,000 --> 00:35:15,000
¿Cómo lo paso?

1121
00:35:15,000 --> 00:35:17,000
¿La unidad es más grande o más pequeña?

1122
00:35:17,000 --> 00:35:18,000
Más pequeña

1123
00:35:18,000 --> 00:35:20,000
¿El hectómetro es más grande que el decámetro?

1124
00:35:20,000 --> 00:35:21,000
Más grande

1125
00:35:21,000 --> 00:35:22,000
Entonces voy a dividir

1126
00:35:22,000 --> 00:35:24,000
voy a correr la coma hacia la izquierda

1127
00:35:24,000 --> 00:35:26,000
porque me voy hacia la izquierda

1128
00:35:26,000 --> 00:35:27,000
¿Cuántos lugares?

1129
00:35:27,000 --> 00:35:29,000
del decámetro al hectómetro

1130
00:35:29,000 --> 00:35:30,000
un lugar

1131
00:35:30,000 --> 00:35:32,000
¿Pero cuántos ceros por lugar?

1132
00:35:32,000 --> 00:35:33,000
tres

1133
00:35:33,000 --> 00:35:34,000
porque estoy en el cúbico

1134
00:35:34,000 --> 00:35:36,000
entonces moveré la coma

1135
00:35:36,000 --> 00:35:38,000
tres lugares a la izquierda

1136
00:35:38,000 --> 00:35:40,000
¿Qué va a dar?

1137
00:35:40,000 --> 00:35:41,000
ochocientos cincuenta y cinco

1138
00:35:41,000 --> 00:35:42,000
no

1139
00:35:42,000 --> 00:35:43,000
ocho mil

1140
00:35:43,000 --> 00:35:45,000
tres lugares a la izquierda

1141
00:35:45,000 --> 00:35:46,000
cero coma

1142
00:35:46,000 --> 00:35:47,000
eso es

1143
00:35:47,000 --> 00:35:48,000
cero coma

1144
00:35:48,000 --> 00:35:50,000
ochocientos cincuenta y tres

1145
00:35:50,000 --> 00:35:52,000
cuatrocientos veinticinco

1146
00:35:52,000 --> 00:35:53,000
ochocientos cincuenta y tres mil

1147
00:35:53,000 --> 00:35:55,000
cuatrocientos veinticinco

1148
00:35:55,000 --> 00:35:57,000
¿Ha quedado claro?

1149
00:35:57,000 --> 00:35:59,000
Entonces esta es la dificultad de los cambios

1150
00:35:59,000 --> 00:36:01,000
¿Qué se dieron cuenta?

1151
00:36:01,000 --> 00:36:03,000
Yo la superficie la mido en metros cuadrados

1152
00:36:03,000 --> 00:36:05,000
la capacidad

1153
00:36:05,000 --> 00:36:07,000
el volumen lo mido en metros cúbicos

1154
00:36:07,000 --> 00:36:09,000
pero se dieron cuenta que

1155
00:36:09,000 --> 00:36:11,000
en realidad lo que

1156
00:36:11,000 --> 00:36:13,000
ocupo, que es el volumen

1157
00:36:13,000 --> 00:36:15,000
es igual a lo que me cabe

1158
00:36:15,000 --> 00:36:17,000
que es la capacidad

1159
00:36:17,000 --> 00:36:19,000
así que hay una relación

1160
00:36:19,000 --> 00:36:21,000
entre

1161
00:36:21,000 --> 00:36:23,000
las unidades

1162
00:36:23,000 --> 00:36:25,000
de volumen y las unidades

1163
00:36:25,000 --> 00:36:27,000
de capacidad

1164
00:36:27,000 --> 00:36:29,000
nosotros habíamos

1165
00:36:29,000 --> 00:36:31,000
definido los litros y los tenemos que

1166
00:36:31,000 --> 00:36:33,000
definir a partir de las unidades de capacidad

1167
00:36:33,000 --> 00:36:35,000
de volumen porque las conozco

1168
00:36:35,000 --> 00:36:37,000
y como yo sé que lo que me cabe

1169
00:36:37,000 --> 00:36:39,000
es lo mismo que ocupo porque tiene que coincidir

1170
00:36:39,000 --> 00:36:41,000
entonces dijeron bueno, bueno

1171
00:36:41,000 --> 00:36:43,000
pues tenemos que definir el litro

1172
00:36:43,000 --> 00:36:45,000
¿Cómo lo definimos?

1173
00:36:45,000 --> 00:36:47,000
A ver, un metro es muy grande

1174
00:36:47,000 --> 00:36:49,000
un metro es así

1175
00:36:49,000 --> 00:36:51,000
un metro cúbico es muy

1176
00:36:51,000 --> 00:36:53,000
grande y es poco operativo

1177
00:36:53,000 --> 00:36:55,000
entonces dijeron vamos a coger

1178
00:36:55,000 --> 00:36:57,000
la siguiente más pequeña del metro que es el decímetro

1179
00:36:57,000 --> 00:36:59,000
y el cubo de un decímetro

1180
00:36:59,000 --> 00:37:01,000
pues un decímetro por un decímetro es algo así

1181
00:37:01,000 --> 00:37:03,000
¿Vale?

1182
00:37:03,000 --> 00:37:05,000
Tiene que ser más pequeño que la baldosa

1183
00:37:05,000 --> 00:37:07,000
porque un metro son tres baldosas

1184
00:37:07,000 --> 00:37:09,000
pues un decímetro sería aproximadamente

1185
00:37:09,000 --> 00:37:11,000
una tercera parte del lado de la baldosa

1186
00:37:11,000 --> 00:37:13,000
¿Lo veis? ¿Lo entendéis?

1187
00:37:13,000 --> 00:37:15,000
Entonces eso sí es un cubo manejable

1188
00:37:15,000 --> 00:37:17,000
que yo suelo tener para medir litros

1189
00:37:17,000 --> 00:37:19,000
entonces dijeron bueno, vamos a ver

1190
00:37:19,000 --> 00:37:21,000
yo voy a coger un cubo

1191
00:37:21,000 --> 00:37:23,000
que tenga

1192
00:37:23,000 --> 00:37:25,000
de lado un decímetro

1193
00:37:25,000 --> 00:37:27,000
un decímetro

1194
00:37:29,000 --> 00:37:31,000
y un decímetro

1195
00:37:31,000 --> 00:37:33,000
es decir

1196
00:37:33,000 --> 00:37:35,000
¿Qué volumen estoy cogiendo?

1197
00:37:35,000 --> 00:37:37,000
¿Uno por uno por uno?

1198
00:37:41,000 --> 00:37:43,000
¿Un qué?

1199
00:37:43,000 --> 00:37:45,000
Un decímetro cúbico

1200
00:37:45,000 --> 00:37:47,000
Muy bien, estoy cogiendo un decímetro cúbico

1201
00:37:47,000 --> 00:37:49,000
de volumen ¿De acuerdo?

1202
00:37:49,000 --> 00:37:51,000
Y ese decímetro cúbico

1203
00:37:51,000 --> 00:37:53,000
de volumen lo voy a llenar de agua

1204
00:37:53,000 --> 00:37:55,000
¿Agua?

1205
00:37:55,000 --> 00:37:57,000
¿Por qué? Porque igual que hemos cogido la tierra

1206
00:37:57,000 --> 00:37:59,000
que es lo único que es común a todos

1207
00:37:59,000 --> 00:38:01,000
¿Cuál es el único líquido que es común a todos

1208
00:38:01,000 --> 00:38:03,000
y que está accesible

1209
00:38:03,000 --> 00:38:05,000
para poder medir? El agua

1210
00:38:05,000 --> 00:38:07,000
porque está en todas las partes de la tierra

1211
00:38:07,000 --> 00:38:09,000
nosotros sin agua no podemos vivir

1212
00:38:09,000 --> 00:38:11,000
así que como todos tenemos agua vamos a coger el líquido más común

1213
00:38:11,000 --> 00:38:13,000
que es el agua

1214
00:38:13,000 --> 00:38:15,000
y entonces lo rellenaron de agua

1215
00:38:15,000 --> 00:38:17,000
hasta el tope

1216
00:38:17,000 --> 00:38:19,000
¿Vale?

1217
00:38:29,000 --> 00:38:31,000
Y a eso lo llamaron litro

1218
00:38:33,000 --> 00:38:35,000
A la cantidad de agua

1219
00:38:35,000 --> 00:38:37,000
la capacidad, la cantidad

1220
00:38:37,000 --> 00:38:39,000
de agua que puedo verter

1221
00:38:39,000 --> 00:38:41,000
en un volumen

1222
00:38:41,000 --> 00:38:43,000
de un decímetro cúbico

1223
00:38:43,000 --> 00:38:45,000
lo llamaron litro

1224
00:38:47,000 --> 00:38:49,000
Tendríamos que saber

1225
00:38:49,000 --> 00:38:51,000
¿Cuántos litros caben en el litro?

1226
00:38:51,000 --> 00:38:53,000
¡Claro! Entonces ¿Qué me pasa?

1227
00:38:53,000 --> 00:38:55,000
¡Ojo! Porque ahí hay que tener

1228
00:38:55,000 --> 00:38:57,000
cuidado porque las del litro van de uno en una

1229
00:38:57,000 --> 00:38:59,000
pero las del metro cúbico

1230
00:38:59,000 --> 00:39:01,000
el decímetro cúbico van de tres en tres

1231
00:39:01,000 --> 00:39:03,000
entonces lo que sucede

1232
00:39:03,000 --> 00:39:05,000
con la tabla

1233
00:39:05,000 --> 00:39:07,000
es algo curioso

1234
00:39:11,000 --> 00:39:13,000
Perdón, el negro

1235
00:39:13,000 --> 00:39:15,000
que lo estábamos poniendo en negro

1236
00:39:17,000 --> 00:39:19,000
Vamos a ver

1237
00:39:19,000 --> 00:39:21,000
cómo queda nuestra tabla

1238
00:39:29,000 --> 00:39:31,000
Aquí yo tengo

1239
00:39:31,000 --> 00:39:33,000
el decímetro cúbico

1240
00:39:33,000 --> 00:39:35,000
y son

1241
00:39:37,000 --> 00:39:39,000
tres barras ¿Verdad?

1242
00:39:41,000 --> 00:39:43,000
Aquí yo tengo

1243
00:39:43,000 --> 00:39:45,000
el metro cúbico

1244
00:39:45,000 --> 00:39:47,000
Aquí yo tengo el metro cúbico

1245
00:39:47,000 --> 00:39:49,000
que son

1246
00:39:49,000 --> 00:39:51,000
otras tres barras

1247
00:39:51,000 --> 00:39:53,000
y aquí yo tengo

1248
00:39:53,000 --> 00:39:55,000
el centímetro cúbico

1249
00:39:55,000 --> 00:39:57,000
que son

1250
00:39:59,000 --> 00:40:01,000
otras tres barras

1251
00:40:05,000 --> 00:40:07,000
y hemos dicho

1252
00:40:07,000 --> 00:40:09,000
voy a poner abajo la equivalencia

1253
00:40:09,000 --> 00:40:11,000
hemos dicho

1254
00:40:11,000 --> 00:40:13,000
que esta que es la unidad

1255
00:40:13,000 --> 00:40:15,000
del decímetro cúbico

1256
00:40:15,000 --> 00:40:17,000
es el litro

1257
00:40:21,000 --> 00:40:23,000
por tanto

1258
00:40:27,000 --> 00:40:29,000
¿Cuál es la siguiente?

1259
00:40:31,000 --> 00:40:33,000
decámetro

1260
00:40:33,000 --> 00:40:35,000
decalitro

1261
00:40:35,000 --> 00:40:37,000
decámetro

1262
00:40:37,000 --> 00:40:39,000
decalitro

1263
00:40:39,000 --> 00:40:41,000
hectolitro

1264
00:40:41,000 --> 00:40:43,000
kilolitro

1265
00:40:45,000 --> 00:40:47,000
vale, pero kilolitro

1266
00:40:47,000 --> 00:40:49,000
fíjate

1267
00:40:49,000 --> 00:40:51,000
yo voy a poner lo que yo ponga aquí

1268
00:40:59,000 --> 00:41:01,000
si no pone nada tengo que completar hasta ahí

1269
00:41:01,000 --> 00:41:03,000
¿Vale?

1270
00:41:03,000 --> 00:41:05,000
y para abajo ¿Qué sería?

1271
00:41:07,000 --> 00:41:09,000
decilitro

1272
00:41:09,000 --> 00:41:11,000
centilitro

1273
00:41:11,000 --> 00:41:13,000
y mililitro

1274
00:41:13,000 --> 00:41:15,000
en realidad yo aquí

1275
00:41:15,000 --> 00:41:17,000
¿Qué puedo leer solamente?

1276
00:41:17,000 --> 00:41:19,000
en esta de aquí arriba

1277
00:41:19,000 --> 00:41:21,000
yo solo puedo leer esta

1278
00:41:21,000 --> 00:41:23,000
porque es la de la coma ¿No?

1279
00:41:23,000 --> 00:41:25,000
solo puedo leer esta

1280
00:41:25,000 --> 00:41:27,000
y solo puedo leer esta

1281
00:41:27,000 --> 00:41:29,000
pues yo sé que

1282
00:41:29,000 --> 00:41:31,000
un metro cúbico es un kilolitro

1283
00:41:31,000 --> 00:41:33,000
si yo tengo

1284
00:41:33,000 --> 00:41:35,000
cinco decímetros cúbicos

1285
00:41:35,000 --> 00:41:37,000
tengo cinco litros

1286
00:41:37,000 --> 00:41:39,000
si yo tengo un centímetro cúbico

1287
00:41:39,000 --> 00:41:41,000
tengo un mililitro

1288
00:41:41,000 --> 00:41:43,000
¿Lo veis?

1289
00:41:43,000 --> 00:41:45,000
son equivalencias

1290
00:41:45,000 --> 00:41:47,000
entonces ¿Qué es lo que hago?

1291
00:41:47,000 --> 00:41:49,000
yo solo puedo hacer las equivalencias

1292
00:41:49,000 --> 00:41:51,000
con eso

1293
00:41:51,000 --> 00:41:53,000
por tanto

1294
00:41:53,000 --> 00:41:55,000
yo me puedo mover en la escala de arriba

1295
00:41:55,000 --> 00:41:57,000
como yo quiera

1296
00:41:57,000 --> 00:41:59,000
pero me tengo que aprender

1297
00:41:59,000 --> 00:42:01,000
una equivalencia

1298
00:42:01,000 --> 00:42:03,000
yo me sé solo esta

1299
00:42:03,000 --> 00:42:05,000
el resto la saco

1300
00:42:05,000 --> 00:42:07,000
entonces que me piden

1301
00:42:07,000 --> 00:42:09,000
que transforme una medida

1302
00:42:09,000 --> 00:42:11,000
de volumen en una medida de capacidad

1303
00:42:11,000 --> 00:42:13,000
¿Vale?

1304
00:42:13,000 --> 00:42:15,000
dime una cantidad

1305
00:42:17,000 --> 00:42:19,000
voy a borrar lo que hay aquí dentro

1306
00:42:21,000 --> 00:42:23,000
la que tú quieras

1307
00:42:23,000 --> 00:42:25,000
33

1308
00:42:25,000 --> 00:42:27,000
¿33 qué?

1309
00:42:31,000 --> 00:42:33,000
metros cúbicos

1310
00:42:33,000 --> 00:42:35,000
centímetros cúbicos

1311
00:42:35,000 --> 00:42:37,000
pon algo más

1312
00:42:37,000 --> 00:42:39,000
cero

1313
00:42:39,000 --> 00:42:41,000
no, que me pongas más cifras

1314
00:42:41,000 --> 00:42:43,000
que haya tres o cuatro cifras

1315
00:42:43,000 --> 00:42:45,000
porque si no vamos a hacer poco

1316
00:42:45,000 --> 00:42:47,000
59

1317
00:42:47,000 --> 00:42:49,000
¿Quieres alguna coma en algún lugar?

1318
00:42:49,000 --> 00:42:51,000
en el primer tres

1319
00:42:51,000 --> 00:42:53,000
te he dado la cantidad

1320
00:42:53,000 --> 00:42:55,000
te falta la unidad

1321
00:42:55,000 --> 00:42:57,000
¿En qué estás midiendo?

1322
00:42:57,000 --> 00:42:59,000
en decímetros cúbicos

1323
00:42:59,000 --> 00:43:01,000
¿Y lo quieres pasar a qué?

1324
00:43:01,000 --> 00:43:03,000
a metros cúbicos

1325
00:43:03,000 --> 00:43:05,000
no, eso no me da problemas

1326
00:43:05,000 --> 00:43:07,000
a capacidad

1327
00:43:07,000 --> 00:43:09,000
a decalitros

1328
00:43:09,000 --> 00:43:11,000
¿Quieres saber cuántos decalitros

1329
00:43:11,000 --> 00:43:13,000
tienes en 3,359 decímetros cúbicos?

1330
00:43:13,000 --> 00:43:15,000
vale

1331
00:43:15,000 --> 00:43:17,000
colócate el 3,359 decímetros cúbicos

1332
00:43:17,000 --> 00:43:19,000
5,3

1333
00:43:19,000 --> 00:43:21,000
¿Dónde pongo el 3?

1334
00:43:23,000 --> 00:43:25,000
en el decímetro

1335
00:43:25,000 --> 00:43:27,000
¿Y luego?

1336
00:43:27,000 --> 00:43:29,000
el 3, el 5 y el 9

1337
00:43:29,000 --> 00:43:31,000
vale

1338
00:43:35,000 --> 00:43:37,000
entonces, el decímetro cúbico

1339
00:43:37,000 --> 00:43:39,000
claro, como lo tienes en decímetros cúbicos

1340
00:43:39,000 --> 00:43:41,000
ya lo tienes en litros

1341
00:43:41,000 --> 00:43:43,000
eso no tiene mucho chiste

1342
00:43:43,000 --> 00:43:45,000
vamos a hacerlo con

1343
00:43:45,000 --> 00:43:47,000
la unidad equivalente

1344
00:43:47,000 --> 00:43:49,000
en metros cúbicos

1345
00:43:49,000 --> 00:43:51,000
vale

1346
00:43:51,000 --> 00:43:53,000
entonces sería aquí cambiado

1347
00:44:01,000 --> 00:44:03,000
¿vale?

1348
00:44:03,000 --> 00:44:05,000
¿de acuerdo?

1349
00:44:05,000 --> 00:44:07,000
incluso sin el 9 si quieres, te pondría un 0

1350
00:44:07,000 --> 00:44:09,000
si no hubiera un 9, pondría un 0

1351
00:44:09,000 --> 00:44:11,000
¿lo ves?

1352
00:44:11,000 --> 00:44:13,000
hay que completar hasta la coma

1353
00:44:13,000 --> 00:44:15,000
entonces, yo tengo 3 metros cúbicos

1354
00:44:15,000 --> 00:44:17,000
yo me sé la equivalencia en decímetros cúbicos

1355
00:44:17,000 --> 00:44:19,000
cada vez que yo tengo

1356
00:44:19,000 --> 00:44:21,000
un decímetro cúbico

1357
00:44:23,000 --> 00:44:25,000
sé que es un litro

1358
00:44:25,000 --> 00:44:27,000
entonces, si yo tengo la tabla

1359
00:44:27,000 --> 00:44:29,000
y me echo a la tabla, está chupado

1360
00:44:29,000 --> 00:44:31,000
porque para pasar a decalitro

1361
00:44:31,000 --> 00:44:33,000
¿dónde tengo que poner la coma?

1362
00:44:35,000 --> 00:44:37,000
pues ya está

1363
00:44:37,000 --> 00:44:39,000
335,9 decalitros

1364
00:44:39,000 --> 00:44:41,000
se acabó el problema

1365
00:44:41,000 --> 00:44:43,000
¿vale?

1366
00:44:43,000 --> 00:44:45,000
normalmente no gasto tanto tiempo en hacer la tabla

1367
00:44:45,000 --> 00:44:47,000
entonces, si no tengo la tabla

1368
00:44:47,000 --> 00:44:49,000
¿qué hago?

1369
00:44:49,000 --> 00:44:51,000
lo mismo, digo ¿vale?

1370
00:44:51,000 --> 00:44:53,000
¿dónde está mi equivalencia?

1371
00:44:53,000 --> 00:44:55,000
en decímetro cúbico

1372
00:44:55,000 --> 00:44:57,000
entonces, lo que hago es que paso por el intermedio

1373
00:44:57,000 --> 00:44:59,000
yo tengo 3,359 metros cúbicos

1374
00:44:59,000 --> 00:45:01,000
¿cuántos decímetros cúbicos son?

1375
00:45:01,000 --> 00:45:03,000
multiplico por mil

1376
00:45:03,000 --> 00:45:05,000
¿vale?

1377
00:45:05,000 --> 00:45:07,000
porque es un lugar y es más pequeña

1378
00:45:07,000 --> 00:45:09,000
así que corro la coma a la derecha

1379
00:45:09,000 --> 00:45:11,000
...

1380
00:45:11,000 --> 00:45:13,000
...

1381
00:45:13,000 --> 00:45:15,000
...

1382
00:45:15,000 --> 00:45:17,000
...

1383
00:45:17,000 --> 00:45:19,000
...

1384
00:45:19,000 --> 00:45:21,000
...

1385
00:45:21,000 --> 00:45:23,000
y como es equivalente

1386
00:45:23,000 --> 00:45:25,000
¿dónde pone decímetro cúbico?

1387
00:45:25,000 --> 00:45:27,000
yo sé que puedo poner

1388
00:45:27,000 --> 00:45:29,000
litro

1389
00:45:29,000 --> 00:45:31,000
y ahora

1390
00:45:31,000 --> 00:45:33,000
de litro a decalitro

1391
00:45:33,000 --> 00:45:35,000
hago una unidad mayor

1392
00:45:35,000 --> 00:45:37,000
corro la coma a un lugar a la izquierda

1393
00:45:37,000 --> 00:45:39,000
luego entonces

1394
00:45:39,000 --> 00:45:41,000
...

1395
00:45:41,000 --> 00:45:43,000
...

1396
00:45:43,000 --> 00:45:45,000
...

1397
00:45:45,000 --> 00:45:47,000

1398
00:45:47,000 --> 00:45:49,000

1399
