Question

Мне срочно нужен ответ на эту задачу: Бревно длиной 8м 1дм распилили на 2 части так, что одна из них в 2 раза больше другой. Скольким дециметрам равна длина каждой части бревна?

Answer 1

Problem Analysis

To solve this problem, we need to find the length of each part of the log after it has been cut into two pieces. We are given that one part is twice as long as the other part. The total length of the log is 8 meters and 1 decimeter.

Solution

Let's assume the length of the shorter part of the log is x decimeters. Since the longer part is twice as long as the shorter part, its length would be 2x decimeters.

To find the length of each part, we need to convert the total length of the log into decimeters.

1 meter is equal to 10 decimeters, so the total length of the log in decimeters would be: 8 meters * 10 decimeters/meter + 1 decimeter = 81 decimeters.

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

x + 2x = 81

Combining like terms, we get:

3x = 81

Dividing both sides by 3, we find:

x = 27

Therefore, the shorter part of the log is 27 decimeters long, and the longer part is twice as long, which is 54 decimeters.

Answer

The length of each part of the log is 27 decimeters and 54 decimeters.
