Final answer:
Sara can make 30 bows from 10 yards of ribbon by dividing the total yards of ribbon (10) by the ribbon needed per bow (1/3).
Step-by-step explanation:
The student wants to know how many bows Sara can make from 10 yards of ribbon, with each bow requiring 1/3 of a yard. To determine the number of bows, perform the following division:
Total yards of ribbon ÷ Ribbon needed per bow = Number of bows
10 yards ÷ 1/3 yard = 30 bows
Sara can make 30 bows from her 10 yards of ribbon.
