If the length of a piece of cloth is 36.25 meter, how many meters of cloth is left? 1

Answer 1

Explanation:

(a) Since each student needs a shirt of the same size, and 2 meters of cloth is required to make one shirt, the total length of cloth required to make shirts for 15 students would be:

Total length of cloth = 15 x 2 = 30 meters

Therefore, 30 meters of cloth would be required to make shirts for 15 students.

(b) If 2 meters of cloth are required to make one shirt, then the number of shirts that can be made from 9 meters of cloth would be:

Number of shirts = 9 / 2 = 4.5 shirts

However, since we cannot make half a shirt, the actual number of shirts that can be made from 9 meters of cloth would be 4 shirts.

To convert the length of cloth required for a shirt into decimal form, we can simply divide the length in centimeters by 100. Therefore, 2 meters of cloth would be equivalent to 200 centimeters, which is 2.00 meters in decimal form.

(c) If the length of a piece of cloth is 36.25 meters, and we use 30 meters to make shirts for 15 students, then the remaining length of cloth would be:

Remaining length of cloth = 36.25 - 30 = 6.25 meters

Therefore, 6.25 meters of cloth would be left.
