Question

Срочно задачу! Рабочему требовалось изготовить 945 деталей за 21 день, он справился с заказом за 15 дней. На сколько больше деталей изготавливал рабочий в день, если производительность была одинаковой?

Answer 1

945:21=45( должен был в день делать)
945:15=63(делал деталей в день)
63-45=18(на столько деталей он переделывал в день)
Ответ:18 деталей

945 : 21 = 45(деталей) в день рабочий должен был изготавливать.
945 : 15 = 63(детали) в день рабочий изготавливал.
63 - 45 = 18 (деталей) изготавливал больше.
Ответ:на 18 деталей в день рабочий больше изготавливал.

Task Analysis

To solve this task, we need to determine how many more parts the worker produced per day compared to the required production rate. The worker completed the order in 15 days instead of the given 21 days, and the productivity remained the same.

Solution

To find out how many more parts the worker produced per day, we can calculate the difference between the total number of parts produced and the number of parts that would have been produced if the worker had worked for 21 days. Then, we divide this difference by the number of days the worker saved.

Let's calculate it step by step:

1. Calculate the total number of parts produced by the worker: - The worker was required to produce 945 parts in 21 days. - Therefore, the required production rate per day is 945 / 21 = 45 parts per day.

2. Calculate the total number of parts that would have been produced if the worker had worked for 21 days: - The required production rate per day is 45 parts. - Therefore, the total number of parts that would have been produced in 21 days is 45 * 21 = 945 parts.

3. Calculate the difference between the total number of parts produced and the number of parts that would have been produced if the worker had worked for 21 days: - The worker produced 945 parts in 15 days. - Therefore, the difference is 945 - 945 = 0 parts.

4. Calculate the number of additional parts produced per day: - The worker saved 6 days (21 days - 15 days). - Therefore, the number of additional parts produced per day is 0 / 6 = 0 parts.

Answer

The worker did not produce any additional parts per day compared to the required production rate. The worker completed the order in 15 days instead of 21 days, but the productivity remained the same.
