Question

реши задачу в куске 32 метров ткани . Для пошива 4 одинаковых пальто требуется 17 метров 20 сантиметров этой ткани. Сколько таких пальто можно сшить из этого куска ? Сколько ткани ещё останется в куске .

Answer 1

Problem Analysis

To solve this problem, we need to determine how many coats can be made from a 32-meter piece of fabric, given that each coat requires 17 meters and 20 centimeters of fabric. We also need to calculate how much fabric will be left over.

Solution

To find out how many coats can be made, we divide the total length of the fabric by the length required for each coat. Then, to calculate the remaining fabric, we subtract the total length of the fabric used for the coats from the initial length of the fabric.

Let's calculate it step by step:

1. Convert the length of the fabric required for each coat to meters: - 20 centimeters = 0.2 meters.

2. Calculate the number of coats that can be made: - Number of coats = Total length of fabric / Length required for each coat. - Number of coats = 32 meters / 17.2 meters. - Number of coats ≈ 1.8604651162790697 coats.

Therefore, approximately 1.86 coats can be made from the 32-meter piece of fabric.

3. Calculate the remaining fabric: - Remaining fabric = Total length of fabric - (Number of coats * Length required for each coat). - Remaining fabric = 32 meters - (1.86 coats * 17.2 meters). - Remaining fabric ≈ 32 meters - 31.992 meters. - Remaining fabric ≈ 0.008 meters.

Therefore, approximately 0.008 meters of fabric will be left over in the 32-meter piece.

Conclusion

From a 32-meter piece of fabric, approximately 1.86 coats can be made, and approximately 0.008 meters of fabric will be left over.
