Angela wants to cut the longer stick to match the shorter one. how much should she cut to make them equal of the lengths is 3 4/5 and 3 1/2

First make sure they have the same denominator, in this problem the LCF is 10 so multiply 4/5 by 2 and 1/2 by 5
This gives us 8/10 and 5/10 now in order to make them equal we have to subtract 3/10 from the long one so it can also equal to 5/10

The correct answer would be "convenience"
