Question

Во время посадки двух участков нового леса руководитель поставил 0,2 участников проекта подносить посадочный материал ,а остальных разделил на две бригады.В первой бригаде было в 9 раз меньше человек,чем во второй.Сколько человек было во второй бригаде,если всего было 250 участников?

Answer 1

Ответ:

Пошаговое объяснение:

Пусть количество людей во второй бригаде равно х человек, тогда в первой бригаде количество людей равно 9х человек.

Составим уравнение:

х+9х=250

10х=250/:10

х=25 человек- во второй бригаде

250-25=225 человек - в первой бригаде

Проверка:

Если во второй бригаде было 225 людей, а в первой 25, то в первой бригаде было в 225:25=9 раз меньше людей - что соответствует условию задачи.

Ответ: в первой бригаде было 25 человек, во второй 225.

Answer 2

Problem Analysis

We are given the following information: - During the planting of two sections of a new forest, the project leader assigned 0.2 participants to handle the planting material, while the rest were divided into two brigades. - The first brigade had 9 times fewer people than the second brigade. - The total number of participants was 250.

We need to determine the number of people in the second brigade.

Solution

Let's denote the number of people in the second brigade as x.

According to the given information, the first brigade had 9 times fewer people than the second brigade. This means that the number of people in the first brigade can be calculated as x/9.

The project leader assigned 0.2 participants to handle the planting material, so the remaining participants were divided into the two brigades. This means that the total number of people in the two brigades is 250 - 0.2 = 249.8.

Since the number of people must be a whole number, we can round 249.8 to the nearest whole number, which is 250.

Now we can set up an equation to solve for x:

x + x/9 = 250

To solve this equation, we can multiply both sides by 9 to eliminate the fraction:

9x + x = 2250

Combining like terms:

10x = 2250

Dividing both sides by 10:

x = 225

Therefore, there were 225 people in the second brigade.

Answer

There were 225 people in the second brigade.
