Question

Решите пропорцией задачу: Трубу разрезали на 2 части длинной 3,6 м и 4,4 м. Во сколько раз часть трубы короче второй? Сколько процентов длины всей трубы составляет длина первой ее части? Решите пожалуйста :)

Answer 1

1)4,4:3,6=1 2/9 (раз)
2)3.6+4.4=8 м-длина всей трубы
   8м-100%                       8:3.6=100:х
3.6м-х%
  
(3.6*100):8=45%

Answer 2

Problem Analysis

We are given a pipe that has been cut into two parts, measuring 3.6 meters and 4.4 meters in length. We need to find the ratio by which the first part is shorter than the second part, as well as the percentage of the total length of the pipe that the first part represents.

Solution

To find the ratio by which the first part is shorter than the second part, we can subtract the length of the first part from the length of the second part and divide the result by the length of the second part.

Let's calculate it step by step:

1. Subtract the length of the first part from the length of the second part: 4.4 - 3.6 = 0.8. 2. Divide the result by the length of the second part: 0.8 / 4.4 ≈ 0.1818.

Therefore, the first part is approximately 0.1818 times shorter than the second part.

To find the percentage of the total length of the pipe that the first part represents, we can divide the length of the first part by the total length of the pipe and multiply the result by 100.

Let's calculate it step by step:

1. Add the length of the first part and the length of the second part: 3.6 + 4.4 = 8. 2. Divide the length of the first part by the total length of the pipe: 3.6 / 8 = 0.45. 3. Multiply the result by 100 to get the percentage: 0.45 * 100 = 45.

Therefore, the length of the first part represents 45% of the total length of the pipe.

Answer

The first part of the pipe is approximately 0.1818 times shorter than the second part. The length of the first part represents 45% of the total length of the pipe.
