Answer:
The greatest number of 15 inches pieces that can be cut from 5 rolls of length 9 feet is: 35
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
As there are 12 inches in one feet, 9 feet will be equal to:
9*12 = 108 inches
Now first of all, we have to see how many 15 inches pieces can be cut from one role
So,
![=(Length\ of\ roll)/(Length\ of\ piece)\\=(108)/(15)\\=7.2](https://img.qammunity.org/2021/formulas/mathematics/college/j7yittr9q6x0545ixbu4khv0vll7j77le3.png)
So the seamstress can cut 7 15-inch long pieces from a roll.
Now given that he has to cut from 5 rolls, the total number of 15-inch pieces will be:
![= 5 * 7 =35](https://img.qammunity.org/2021/formulas/mathematics/college/aws6gbsu1f4szxxqo7bfyl9bnfr2nggm9v.png)
Hence,
The greatest number of 15 inches pieces that can be cut from 5 rolls of length 9 feet is: 35
