Question

Which equation calculates the number of 1818-foot pieces you can cut from 55 feet of ribbon?

Answer 1

ANSWER

$5\div\frac{1}{8}=40$

EXPLANATION

The ribbon is 5 feet long, and we want to cut 1/8-foot pieces of it. To know how many pieces we can get, we have to divide the length of the ribbon by the length of each piece,

$5\div\frac{1}{8}$

To divide, we can use the KCF method:

• K,eep the first fraction (in this case it is a whole number)

,

• C,hange the division sign by a multiplication sign

,

• F,lip the second fraction

So we have,

$5\div\frac{1}{8}=5\times\frac{8}{1}=5\times8$

And 5 times 8 is 40. Hence, the answer is,

$5\div\frac{1}{8}=40$
