Question

В двух мастерских отремонтировали 720 изделий. В одной мастерской работало 5 человек, а в другой - 3. Сколько изделий отремонтировала каждая мастерская, при условии, что производительность труда у них была одинаковая? (Каждое действие с пояснением).

Answer 1

Ответ:

1) 5+3=8 человек работало в обоих мастерских

2) 720:8=90 изделий сделал один человек

3) 5*90=450 изделий сделали в 1й мастерской

4) 3*90=270 изделий сделали во 2й мастерской

Problem Analysis

We are given that two workshops repaired a total of 720 items. One workshop had 5 workers, while the other had 3 workers. We need to determine how many items each workshop repaired, assuming that the labor productivity was the same in both workshops.

Solution

Let's assume that the number of items repaired by the workshop with 5 workers is represented by x, and the number of items repaired by the workshop with 3 workers is represented by y.

Since the labor productivity is the same in both workshops, we can set up the following equation:

5x = 3y

To solve for x and y, we need to find values that satisfy this equation and add up to a total of 720 items.

Solving the Equation

To find the values of x and y, we can use trial and error or algebraic methods.

Let's start with trial and error:

- If we assume that the workshop with 5 workers repaired 100 items, then the workshop with 3 workers would have repaired 60 items. However, this does not add up to a total of 720 items. - If we assume that the workshop with 5 workers repaired 200 items, then the workshop with 3 workers would have repaired 120 items. This also does not add up to a total of 720 items. - If we assume that the workshop with 5 workers repaired 300 items, then the workshop with 3 workers would have repaired 180 items. This still does not add up to a total of 720 items. - If we assume that the workshop with 5 workers repaired 400 items, then the workshop with 3 workers would have repaired 240 items. This still does not add up to a total of 720 items. - If we assume that the workshop with 5 workers repaired 500 items, then the workshop with 3
