150·100÷30=500м длина 3 части

Answer 2

Problem Analysis

We are given a wire that has been divided into three parts. The length of the first part is 240m. The length of the second part is 5/8 of the length of the first part. The length of the third part is 30% of the length of the third part. We need to find the lengths of the second and third parts.

Solution

Let's calculate the lengths of the second and third parts step by step.

1. Length of the second part: - The length of the second part is 5/8 of the length of the first part. - Therefore, the length of the second part is (5/8) * 240m. - Calculating this, we get: ``` Length of the second part = (5/8) * 240m = 150m ```

2. Length of the third part: - The length of the third part is 30% of the length of the first part. - Therefore, the length of the third part is (30/100) * 240m. - Calculating this, we get: ``` Length of the third part = (30/100) * 240m = 72m ```

Answer

The length of the second part is 150m and the length of the third part is 72m.
