Kyle used 3/5 yard of wire to hang one painting and 1/4 yard of wire to hang another painting. how much wire did Kyle use in all?
First, we want to make sure that 3/5 and 1/4 have the same common denominator. Multiply 3/5 by 4/4 and 1/4 by 5/5, we get that 3/5+1/4 = 12/20+5/20 = 17/20. Hence, Kyle used 17/20yds of wire in all.
