Answer:
32 3/5 yards
Step-by-step explanation:
First, you take 9×1 2/3 because there are 9 skirts and each requires 1 2/3 yards of fabric. This equals 15.
Next, you take 8×2 1/5 because there are 8 trousers and each requires 2 1/5 yards of fabric. This equals 17 3/5.
Then you add those numbers to find your total, which equals 32 3/5.
