Calculation of Fabric Used for Each Dress

To calculate the amount of fabric used for each dress, we need to subtract the amount of fabric left after sewing from the initial amount of fabric.

Given: - Initial amount of fabric: 100 meters - Number of identical children's dresses sewn: 21 - Number of identical women's dresses sewn: 17 - Amount of fabric left after sewing: 7 meters

To find the amount of fabric used for each dress, we can follow these steps:

1. Calculate the total amount of fabric used for the dresses: - Total fabric used = Initial fabric - Fabric left after sewing - Total fabric used = 100 meters - 7 meters - Total fabric used = 93 meters

2. Calculate the average amount of fabric used per dress: - Average fabric used per dress = Total fabric used / (Number of children's dresses + Number of women's dresses) - Average fabric used per dress = 93 meters / (21 + 17) - Average fabric used per dress = 93 meters / 38 - Average fabric used per dress ≈ 2.447 meters

Therefore, approximately 2.447 meters of fabric were used for each dress.
