Answer:
You need 7 3/4 yards of blue silk to make both dresses
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Blue silk needed to make one bridesmaid's dress = 4 1/8 yards
Blue silk needed to make another bridesmaid's dress = 3 5/8 yards
2. How many yards of blue silk do you need to make both dresses?
Yards of blue silk needed to make both dresses = Blue silk needed to make one bridesmaid's dress + Blue silk needed to make another bridesmaid's dress
Yards of blue silk needed to make both dresses = 4 1/8 + 3 5/8
Yards of blue silk needed to make both dresses = 33/8 + 29/8
Yards of blue silk needed to make both dresses = 62/8 = 7 6/8 = 7 3/4
You need 7 3/4 yards of blue silk to make both dresses
