Question

If there are 50 dogs and 30 cats at a pet daycare, fill out all of the possible ratios of dogs to cats that could be made.

Answer 1

50/30, 25/15, 10/6, 5/3

Explanation:

To answer the question, you need to decompose the numerator and denominator into simple factors and see what combinations are possible.

50:2 = 25
25:5 = 5
5:5 = 1
Multipliers for 50: 2, 5, 5

30:2 = 15
15:3 = 5
5:5 = 1
Multipliers for 30: 2, 3, 5

Common multipliers for dogs and cats: 2 and 5
So we can divide the our ratio by 2, by 5 and by their product 2 x 5 = by 10.

We get the following series:
50/30, 25/15, 10/6, 5/3
