Question

Sammi had a total of 25 ft of ribbon. She cut off 13 ½ feet to keep, the remaining fabric she cut into 3 inch sections to make ribbons. How many ribbons would she be able to make?

Answer 1

First, find the total length of the remaining fabric by substracting 13 1/2 from 25:

`\begin{gathered} 25-13(1)/(2) \\ =25-13-(1)/(2) \\ =12-(1)/(2) \\ =11(1)/(2) \end{gathered}`

Since one feet equals 12 inches, multiply 11 1/2 by 12 to find the total length of the remaining fabric in inches:

`\begin{gathered} 11(1)/(2)*12=11*12+(1)/(2)*12 \\ =132+(12)/(2) \\ =132+6 \\ =138 \end{gathered}`

Since each ribbon takes 3 inches, divide 138 over 3 to find the total amount of ribbons that can be made:

`(138)/(3)=46`

Therefore, Sammi is able to make 46 ribbons.
