Question

Zoe used 3/8 of her ribbon to wrap a present. If she uses 9 feet of ribbon for the present how much ribbon did Zoe have it first?

Answer 1

Let the total ribbon Zoe had was x feet.

Out of x feet, she used 3/8 part of it.

Hence,
`(3x)/(8)`

3/8 part of the original ribbon is equal to 9 feet.

Hence, we get

`(3x)/(8) = 9`

=> Multiply 8 on both sides.

`3x=72`

Divide both sides by 3

`(3x)/(3)=(72)/(3)`

`x=24 ft`

Zoe had 24 feet of ribbon in starting... Answer
