Question

Три токаря сделали несколько деталей. Первый сделал четверть всех деталей, второй треть всех деталей. Во сколько раз третий токарь сделал больше деталей, чем первый? Какую часть детали, сделанные вторым токарем, составляют от деталей, сделанных третьим токарем?​

Answer 1

Ответ:

Пошаговое объяснение:

1/4+1/3=3/12+4/12=7/12 2 токаря

12/12-7/12=5/12 3 токарь

5/12÷1/4=5/12×4/1=5/3=1 2/3 в 1 2/3 третий токарь сделал больше, чем первый

1/3÷5/12= 1/3×12/5=4/5 составляют детали сделанные 2 токарь от деталей , сделанных третьим токарем

Question Analysis

The question asks for a detailed explanation of a scenario involving three lathe operators who have made several parts. The first operator made a quarter of all the parts, the second operator made a third of all the parts. The question asks how many times more parts the third operator made compared to the first operator, and what proportion of the parts made by the second operator is made up of the parts made by the third operator.

Answer

To solve this problem, let's assume that the total number of parts made is 100.

The first operator made a quarter of all the parts, which is 25 parts (100 * 1/4 = 25).

The second operator made a third of all the parts, which is approximately 33.33 parts (100 * 1/3 ≈ 33.33).

To find out how many times more parts the third operator made compared to the first operator, we need to subtract the number of parts made by the first operator from the total number of parts made by the second operator.

So, the third operator made approximately 33.33 - 25 = 8.33 parts more than the first operator.

To find out what proportion of the parts made by the second operator is made up of the parts made by the third operator, we need to divide the number of parts made by the third operator by the number of parts made by the second operator.

So, the proportion of the parts made by the second operator that is made up of the parts made by the third operator is approximately 8.33 / 33.33 ≈ 0.25, or 25%.

Therefore, the third operator made approximately 8.33 parts more than the first operator, and the parts made by the third operator make up approximately 25% of the parts made by the second operator.

Please note that the calculations above are based on the assumption that the total number of parts made is 100. If the actual total number of parts made is different, the calculations will need to be adjusted accordingly.
