Calculating Fabric Usage for Girls' Costumes

To find out how many meters of fabric were used for sewing costumes for girls, we can use the information provided about the total fabric used and the portion used for boys' costumes.

Given: - Total fabric used for both boys' and girls' costumes: 240 meters - Portion of fabric used for boys' costumes: 3/8 of the total fabric

We can calculate the amount of fabric used for girls' costumes using the following steps:

1. Calculate the amount of fabric used for boys' costumes. 2. Subtract the amount used for boys' costumes from the total fabric to find the amount used for girls' costumes.

Calculation Steps

1. Calculate Fabric Used for Boys' Costumes: - Total fabric used: 240 meters - Portion used for boys' costumes: 3/8 of the total fabric - Calculation: 240 meters * 3/8 = 90 meters

Therefore, 90 meters of fabric were used for boys' costumes.

2. Calculate Fabric Used for Girls' Costumes: - Total fabric used: 240 meters - Fabric used for boys' costumes: 90 meters - Calculation: 240 meters - 90 meters = 150 meters

Therefore, 150 meters of fabric were used for sewing costumes for girls.

So, the amount of fabric used for sewing costumes for girls is 150 meters.
