Problem Statement

Для каждого из двух кабинетов получили по 15 комплектов ученической мебели. За два дня рабочий распаковал и собрал 10 комплектов. Сколько комплектов ученической мебели осталось собрать? Решите задачу двумя способами.

Solution 1: Subtraction

To find out how many sets of student furniture are left to assemble, we can subtract the number of sets already assembled from the total number of sets received.

Given: - Total number of sets received for each cabinet: 15 - Number of sets assembled in two days: 10

To find the number of sets left to assemble, we can subtract the number of sets assembled from the total number of sets received: Number of sets left to assemble = Total number of sets received - Number of sets assembled

Substituting the given values: Number of sets left to assemble = 15 - 10 = 5 sets

Therefore, there are 5 sets of student furniture left to assemble.

Solution 2: Multiplication

Another way to solve this problem is by using multiplication.

Given: - Total number of sets received for each cabinet: 15 - Number of sets assembled in two days: 10

To find the number of sets left to assemble, we can multiply the number of sets assembled per day by the number of days remaining and subtract it from the total number of sets received: Number of sets left to assemble = (Number of sets assembled per day) x (Number of days remaining)

Substituting the given values: Number of sets left to assemble = (10 sets/day) x (2 days) = 20 sets

Therefore, there are 20 sets of student furniture left to assemble.

Conclusion

In conclusion, there are two ways to solve the problem. Using subtraction, we find that there are 5 sets of student furniture left to assemble. Using multiplication, we find that there are 20 sets of student furniture left to assemble.
