Fractions and Proportions

A porportion, division or ratio is computed as the fraction a/b. In some cases, we want to compare parts or subsets of elements with the whole set. If n is the total number of elements of the set, and a,b,c,.. are subsets, then a/n, b/n, c/n express the portions of n each subset has.

We know Renee rode in the frontseat for one fourth of the trip. It's 1/4 proportion.  

If we know the trip was 7 hours long, then Renee rode in the frontseat a total of

It's one hour and 45 minutes
