1 1/3 yards of fabric per shirt
Explanation:
Unit rate is a rate per 1
If you want to find the unit rate of yards per shirt, you do 4 2/3 divided by 3 1/2
Meanwhile if you want to find the unit rate of SHIRTS per yards of fabric, you do 3 1/2 divided by 4 2/3
IN THIS CASE, we will use the unit rate YARDS PER SHIRT:
4 2/3 ÷ 3 1/2
= 14/3 x 2/7
= 28/21
=1 1/3
Hope this helps!
