One group (A) contains 615 people. Three-fifths of the people in group A will be selected to win $50 fuel cards. There is another group (B) in a nearby town that will receive the same number of fuel cards, but there are 526 people in that group. What will be the ratio of nonwinners in group A to nonwinners in group B after the selections are made? Express your ratio as a fraction or with a colon.

Step by Step:
Group A:
First, figure out 1/5 of the people in group A. ( 615/5 = 123 )
Find 2/5 ( the amount of people who lost ) ( 123*2 = 246 )
Group B:
They received the same amount of fuel cards, so you take 526 - 369 ( 3/5 of the last group, or the winners, which is the amount of cards they received ) = 157.
