Question

Математика 4 класс Козлова.задача: Рабочий должен был изготовить изготовить 64 детали после работы ему осталось сделать 48 Сколько часов он изготовит оставшиеся детали если будет работать с производительностью

Answer 1

64-48=16(деталий)
16:2=8(деталий)
48:8=6(часов)
Ответ:6часов.

Answer 2

64-48=16 (дет.) изготовил рабочий за 2 часа
16/2=8 (дет.) изготавливает рабочий за 1 час
48/8=6 (час.) понадобится рабочему чтобы изготовить оставшиеся детали.

Answer 3

Problem:

The problem states that a worker was supposed to make 64 parts, but after work, he still has 48 parts left to make. The question asks how many hours it will take him to make the remaining parts if he works at a certain productivity rate.

Solution:

To solve this problem, we need to find the worker's productivity rate and then use it to calculate the time required to make the remaining parts.

Let's assume that the worker's productivity rate is x parts per hour.

According to the problem, the worker has already made 64 - 48 = 16 parts.

To find the time required to make the remaining 48 parts, we can set up the following equation:

16 + x * t = 48

Where: - 16 represents the parts the worker has already made, - x represents the worker's productivity rate (parts per hour), - t represents the time required to make the remaining parts (in hours), and - 48 represents the remaining parts.

Now, let's solve the equation for t.

16 + x * t = 48

Subtracting 16 from both sides:

x * t = 48 - 16

Simplifying:

x * t = 32

Dividing both sides by x:

t = 32 / x

Therefore, the time required to make the remaining parts is 32 / x hours.

Now, we need to find the value of x (productivity rate) to calculate the time.

Unfortunately, the given information does not provide the productivity rate. Without this information, we cannot determine the exact time required to make the remaining parts.

To solve the problem, we need additional information about the worker's productivity rate.
