Question

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

Answer 1

1) 75 - 56 = 19 - разница в числе курток.

2) 57 : 19 = 3 - метра ткани на 1 куртку.

3) 56 х 3 = 168 - метров ткани на куртки для девочек.

4) 75 х 3 = 225 - метров ткани на куртки для мальчиков

Answer 2

75-56=19  курток разница
57:19=3 м. расход на одну куртку 
56*3=168 м. израсходовали на куртки для девочек
75*3=225 м. израсходовали на куртки для мальчиков

Answer 3

Task: Calculating Fabric Usage for Jackets

To solve this task, we need to determine the amount of fabric used for the jackets made for girls and boys separately. Let's denote the fabric usage for each girl's jacket as 'x' and the fabric usage for each boy's jacket as 'y'.

According to the information given: - 56 jackets were made for girls. - 75 jackets were made for boys. - The fabric usage for each boy's jacket was 57 meters more than the fabric usage for each girl's jacket.

To find the fabric usage for the jackets made for girls, we can set up the following equation: 56x + 57 = 75y

Now, let's solve this equation to find the values of 'x' and 'y'.

Solution:

To solve the equation, we can use the method of substitution. We'll solve for 'x' in terms of 'y' and then substitute it back into the equation.

From the equation: 56x + 57 = 75y - Subtract 57 from both sides: 56x = 75y - 57 - Divide both sides by 56: x = (75y - 57) / 56

Now, we can substitute this value of 'x' back into the equation to find the fabric usage for the jackets made for girls.

Substituting x = (75y - 57) / 56 into the equation: 56((75y - 57) / 56) + 57 = 75y

Simplifying the equation: 75y - 57 + 57 = 75y 75y = 75y

This equation is true for any value of 'y'. Therefore, we can conclude that the fabric usage for the jackets made for girls is (75y - 57) / 56 meters.

Similarly, the fabric usage for the jackets made for boys is 'y' meters.

Unfortunately, without the specific value of 'y', we cannot determine the exact amount of fabric used for the jackets made for girls and boys.
