Answer 2

Answer: There are 3 strips that can be cut from the roll of ribbon.

Explanation:

since we have given that

Length of a ribbon is given by

`7(1)/(2)\ ft\\\\=(15)/(2)\ ft`

Length of pieces of ribbon cut into strips is given by

`2(1)/(2)\ ft\\\\=(5)/(2)\ ft`

So, we need to find the number of strips that can be cut is given by

`\text{ Number of strips }=\frac{\text{Length of roll}}{\text{ Length of strip}}\\\\=((15)/(2))/((5)/(2))\\\\=(15* 2)/(2* 5)\\\\=(15)/(5)\\\\=3`

Hence, there are 3 strips that can be cut from the roll of ribbon.
