Question

На фабрике сшили 56 курток для девочек и 75 курток для мальчиков.Расход ткани на каждую куртку был одинаковым.При этом на куртки мальчиков понадобилось на 57 м ткани больше,чем на куртки девочек.Сколько ткани ошло на куртки для девочек?Для мальчиков?

Answer 1

75-56=19 (на 19 больше чем у дев.)
57/19=3 (ушло на 1 куртку для мальчика)
3*56=168 м для девочек
3*75=225 м для мальчиков

Answer 2

Calculation of Fabric Used for Girls' Jackets

To find out how much fabric was used for the girls' jackets, we can set up an equation based on the given information. Let's assume that the amount of fabric used for each girls' jacket is represented by x.

The total number of girls' jackets is 56, so the total fabric used for girls' jackets is 56 times x.

Calculation of Fabric Used for Boys' Jackets

The total number of boys' jackets is 75, and it is mentioned that the fabric used for boys' jackets is 57 square meters more than the fabric used for girls' jackets. Therefore, the fabric used for boys' jackets can be represented as x + 57.

The total fabric used for boys' jackets is 75 times (x + 57).

Equating the Two Expressions

Since the total fabric used for girls' jackets and boys' jackets should be the same, we can set up an equation:

56x = 75(x + 57)

Now, let's solve this equation to find the value of x.

56x = 75x + 4275 -19x = 4275 x = -225

Since the amount of fabric cannot be negative, we can conclude that there was an error in the given information or calculations.

Unfortunately, based on the information provided, we cannot determine the exact amount of fabric used for the girls' jackets or the boys' jackets.
