Question

Casey has 8 1/2 yards of fabric. She uses 2 1/2 yards to make pillows and 3 yards to make curtains. How much fabric is remaining?

A) 2 yards

B) 2 1/2 yards

C) 3 yards

D) 3 1/2 yards

Answer 1

2.5+3=5.5

8.5-5.5=3

Your answer is C

Answer 2

Option C) 3 yards.

Explanation:

The length of the fabric that Casey had =
`8(1)/(2)` yards

She used some to make pillows =
`2(1)/(2)` yards

and she used fabric to make curtains = 3 yards

She used total fabric =
`2(1)/(2)` + 3

=
`(5)/(2)` + 3

=
`(5+6)/(2)`

=
`(11)/(2)`

=
`5(1)/(2)` yards

Now to calculate the remaining fabric, we will subtract the used fabric from the total fabric.

`8(1)/(2)` -
`5(1)/(2)`

=
`(17)/(2)` -
`(11)/(2)`

=
`(17-11)/(2)`

=
`(6)/(2)`

= 3 yards

3 yards fabric is remaining.
