First, we add the amounts she used.
1 1/2 + 1 1/8
We need a common denominator for the fractions. It is 8.
1 1/2 + 1 1/8 = 1 4/8 + 1 1/8 = 2 5/8
She used 2 5/8 yd.
Now we subtract 2 5/8 yd from 5 yd to find out how much she has left.
5 - 2 5/8
There is no fraction with the 5, so we borrow 1 from 5, leaving 4, and we write the 1 as fraction 8/8. Then we subtract the whole numbers, and we subtract the fractions.
5 - 2 5/8 = 4 8/8 - 2 5/8 = 2 3/8
Answer: She has 2 3/8 yd left.
