Tenemos 2000 baldosascon las que nos proponrmos embaldosar dos habitaciones.Para la 1ª gastamos 3/5 de ellas,y con la 2ª,3/4de l
Setler79 [48]

Answer:

En la primera habitación son usadas 1200 baldosas.

En la segunda habitación son usadas 600 baldosas.

Sobraron 200 baldosas.

Step-by-step explanation:

Tienes 2000 baldosas, con las que se propone embaldosar dos habitaciones.

Para la primera habitación se han gastado \frac{3}{5} de las baldosas. Esto se expresa como:

\frac{3}{5}*2000

Para multiplicar una fracción por un número entero, el número entero n se puede escribir como la fracción \frac{n}{1}. Luego se multiplica los numeradores y denominadores. En este caso:

\frac{3}{5}*2000=\frac{3}{5}*\frac{2000}{1} =\frac{3*2000}{5*1} = \frac{6000}{5}

Para reducir la fraccion, divide 40 entre 10

\frac{6000}{5} = 6000 ÷5= 1200

Entonces <u><em>en la primera habitación son usadas 1200 baldosas.</em></u> Por lo que las que quedan se calcula como:

2000 - 1200= 800 baldosas

De esta cantidad de baldosas que quedaron, \frac{3}{4} son usadas para embaldosar la segunda habitación.  Esto se expresa como:

\frac{3}{4}*800

Resolviendo de igual manera que en el caso de la primer habitación se obtiene:

\frac{3}{4}*800=\frac{3}{4}*\frac{800}{1} =\frac{3*800}{4*1} =\frac{2400}{4}= 2400 ÷ 4= 600

Entonces <u><em>en la segunda habitación son usadas 600 baldosas.</em></u> Por lo que, teniendo en cuenta que se tenían 800 baldosas que quedaron de la primera habitación, las baldosas restantes se calculan como:

800 - 600= 200 baldosas

<u><em>Sobraron 200 baldosas.</em></u>
