Question

Фабрика произвела в апреле 42500 пар обуви.Сколько всего пар обуви произвела фабрика в мае,если мужской обуви было выпущено на 1890 пар меньше,а женской обуви на 2500 пар больше,чем в апреле?(решите двумя способами)сделайте как пропорции

Answer 1

42500+2500-1890=43110 пар обуви произвела фабрика в мае

Answer 2

Calculation using Proportions:

To find the total number of shoes produced by the factory in May, we can use proportions based on the information provided.

Let's denote the number of shoes produced in April as A.

According to the given information: - The number of men's shoes produced in May is 1,890 pairs less than in April. - The number of women's shoes produced in May is 2,500 pairs more than in April.

Let's denote the number of men's shoes produced in May as M and the number of women's shoes produced in May as W.

We can set up the following proportions:

Men's Shoes: A - M = 1,890

Women's Shoes: W - A = 2,500

To solve these proportions, we can cross-multiply and solve for the unknowns.

Men's Shoes: A - M = 1,890 A = M + 1,890

Women's Shoes: W - A = 2,500 W = A + 2,500

Now, let's substitute the value of A from the first equation into the second equation:

W = (M + 1,890) + 2,500 W = M + 4,390

Since we want to find the total number of shoes produced in May, we need to add the number of men's and women's shoes:

Total shoes produced in May = M + W Total shoes produced in May = M + (M + 4,390) Total shoes produced in May = 2M + 4,390

To find the value of M, we need more information. Unfortunately, the given information does not provide the exact number of men's shoes produced in April or any other relevant data. Therefore, we cannot calculate the total number of shoes produced in May using proportions.

Alternative Calculation:

Since we cannot calculate the total number of shoes produced in May using proportions, let's consider an alternative approach.

Given that the factory produced 42,500 pairs of shoes in April, we know that this number includes both men's and women's shoes.

According to the given information, the number of men's shoes produced in May is 1,890 pairs less than in April, and the number of women's shoes produced in May is 2,500 pairs more than in April.

To find the total number of shoes produced in May, we need to adjust the number of men's and women's shoes produced in April.

Men's Shoes: The number of men's shoes produced in May is 1,890 pairs less than in April. Therefore, the number of men's shoes produced in May is: 42,500 - 1,890 = 40,610 pairs.

Women's Shoes: The number of women's shoes produced in May is 2,500 pairs more than in April. Therefore, the number of women's shoes produced in May is: 42,500 + 2,500 = 45,000 pairs.

To find the total number of shoes produced in May, we add the number of men's and women's shoes: 40,610 + 45,000 = 85,610 pairs.

Therefore, the factory produced a total of 85,610 pairs of shoes in May.

Please note that the alternative calculation assumes that the number of men's and women's shoes produced in April is equal. If this assumption is not valid, the calculation may not be accurate.
