Question

Решитьзадачу.В трёх цехах фабрики работают 480 человек.Число людей,работающих во втором цехе,состовляет 36% числа людей первого цеха,а число людей,работающих в третьем цехе,состовляет 2/3 числа людей второго цеха.Сколько человек работает в каждом из этих цехов?

Answer 1

x-кол-во людей в 1 цехе; 0.36х-во 2; 2/3 *0.36х-в 3 цехе  х+0.36х+2/3*0.36х=480  х+0.36+0.24х=480 1.6х=480 х=300 в 1 цехе 0.36*300=108 во 2 цехе 0.24*300=72 в 3 цехе вроде так

Answer 2

Хчел - работает в первом цехе, 0,36 х - во втором, и 2/3*0,36х=0,24х - в третьем. тк всего работают 480 человек составим уравнение.

х+0,36х+0,24х=480. 1, 6х=480; х=300, 0,36х=108; 0,24х=72.

Ответ в первом цехе - 300чел, во втором -108чел., в третьем - 72чел.

Answer 3

Problem Analysis

We are given the total number of people working in three different workshops of a factory. The number of people in the second workshop is 36% of the number of people in the first workshop, and the number of people in the third workshop is 2/3 of the number of people in the second workshop. We need to find the number of people working in each workshop.

Solution

Let's denote the number of people in the first workshop as x.

According to the problem, the number of people in the second workshop is 36% of the number of people in the first workshop. So, the number of people in the second workshop is 0.36 times x.

Similarly, the number of people in the third workshop is 2/3 of the number of people in the second workshop. So, the number of people in the third workshop is (2/3) times 0.36 times x.

To find the number of people in each workshop, we can substitute the values and solve the equation.

Let's calculate it step by step:

1. Let's denote the number of people in the first workshop as x. 2. The number of people in the second workshop is 36% of the number of people in the first workshop, which is 0.36 times x. 3. The number of people in the third workshop is 2/3 of the number of people in the second workshop, which is (2/3) times 0.36 times x.

Now, let's solve the equation:

x + 0.36x + (2/3)(0.36x) = 480

Simplifying the equation:

1x + 0.36x + (2/3)(0.36x) = 480

1x + 0.36x + (2/3)(0.36x) = 480

1x + 0.36x + 0.24x = 480

1.6x = 480

Dividing both sides of the equation by 1.6:

x = 480 / 1.6

x = 300

So, the number of people in the first workshop (x) is 300.

Now, let's calculate the number of people in the second workshop and the third workshop:

- The number of people in the second workshop is 0.36 times x = 0.36 * 300 = 108. - The number of people in the third workshop is (2/3) times 0.36 times x = (2/3) * 0.36 * 300 = 72.

Therefore, the number of people working in each workshop is as follows: - First workshop: 300 people - Second workshop: 108 people - Third workshop: 72 people

Answer

The number of people working in each workshop is as follows: - First workshop: 300 people - Second workshop: 108 people - Third workshop: 72 people
