Answer:
The greatest number of 15 inches pieces that can be cut from 5 rolls of length 9 feet is: 35
Step-by-step explanation:
Given
Total length of one roll of ribbon = 9 feet
As the pieces have to be cut into inches, we will convert the measurement in feet to inches

Hence,
The greatest number of 15 inches pieces that can be cut from 5 rolls of length 9 feet is: 35
