Answer:
4 cats : 5 dogs is your answer
Step-by-step explanation:
Divide common factors from both ratios. Find the factors:
12: 1, 2, 3, 4, 6
15: 1, 3, 5, 15
The greatest common factor is 3 (as they are factors for both). Divide 3 from both numbers:
12:15
(12)/3 : (15)/3
4:5
4 cats : 5 dogs is your answer
