Question

erica bought 3 1/2 yards of fabric. if she uses 2/3 of the fabric to make a curtain, how much will she have left?

Answer 1

First we will make 3 1/2 to improper fraction:
`3 (1)/(2) = (7)/(2)` Then:
`(7)/(2)- (2)/(3) * (7)/(2)= (7)/(2) - (14)/(6) = (21)/(6)- (14)/(6) = (7)/(6)=1 (1)/(6)`
Answer: 1 1/6 yards.
