Ant is 1/4" and aphid is 3/32" so how many times longer is the ant then the aphid

1/4 - 3/32

you have to find a common denominator. In this case it will be 32.

4 * 8 = 32

It will turn into:

8/32 - 3/32.

now all you have to do is subtract the numerators.

8 - 3 = 5.

your answer is

5/32

1/4 and 3/32 = 8/32 and 3/32

8/32 / 3/32 = 2 2/3 times longer

2 2/3 times longer

or

2 times longer
