С книжного склада отправили в школы города 28 800 учебников. В первую школу отправили четвёртую часть этих учебников, во вторую ▬ 6 300 учебников, а остальные учебники были отправлены в 3 школы, поровну в каждую. Сколько учебников получила каждая из этих трёх школ?

Answer 1

28 800:4=7 200 в первую школу
28 800-7 200-6 300=15 300 отправлено в 3 школы

Answer 2

Problem Analysis

We are given that 28,800 textbooks were sent from a book warehouse to schools in a city. The first school received one-fourth of these textbooks, the second school received 6,300 textbooks, and the remaining textbooks were sent to three other schools equally. We need to determine how many textbooks each of these three schools received.

Solution

To solve this problem, we can follow these steps: 1. Calculate the number of textbooks sent to the first school. 2. Calculate the number of textbooks sent to the second school. 3. Calculate the number of textbooks sent to the three other schools combined. 4. Divide the number of textbooks sent to the three other schools equally among them.

Let's calculate the number of textbooks each school received step by step.

1. Calculate the number of textbooks sent to the first school: - The first school received one-fourth of the total textbooks. - One-fourth of 28,800 textbooks is 28,800 / 4 = 7,200 textbooks.

2. Calculate the number of textbooks sent to the second school: - The second school received 6,300 textbooks.

3. Calculate the number of textbooks sent to the three other schools combined: - The remaining textbooks after sending to the first and second schools are 28,800 - 7,200 - 6,300 = 15,300 textbooks.

4. Divide the number of textbooks sent to the three other schools equally among them: - Each of the three other schools received an equal share of the remaining textbooks. - The number of textbooks each of the three other schools received is 15,300 / 3 = 5,100 textbooks.

Therefore, each of the three other schools received 5,100 textbooks.

Answer

The first school received 7,200 textbooks, the second school received 6,300 textbooks, and each of the three other schools received 5,100 textbooks.
