<h3>What is ratio?</h3>
A ratio is the  comparison of the  two numbers bydivision.
Taking the first two outputs, or the  -1/8 and -1/4, we can divide not the second one by the first one to find the
ratio:
-1/4-1/8
When dividing fractions, we multiply by the reciprocal:
-1/4x-8/1
To multiply fractions, multiply straight across:
(-1x-8)/(4x1) 8/4=2
