Question

an average ant is 1/4 of an inch long. an average aphid is 3/32 of an inch long. how many times longer is the ant than the aphid

Answer 1

First find the common denominator.  In this case, you would want to use 32.  So, 1/4 = 8/32.  So, an ant is 8/32 of an inch and an aphid is 3/32 of an inch.  Now to find the difference, you subract.  8/32 - 3/32 = 5/32.  So the answer is, the ant is 5/32 of an inch longer.
