Answer:
There are 45 dogs, 27 cats
Step-by-step explanation:
Write and solve an equation of ratios. The "cat ratio" is 3/27 and the "dog ratio" is 5/d:
Then
3 5
------ = -----
27 d
Through cross-multiplication, we get 3d = 135, or d = 45
There are 45 dogs, 27 cats. Notice that 27/45 = 3/5, as expected.
I would assume 1/5 is your answer. As 1/5+1/5+1/5+1/5+1/5 = 5/5 which is 1.
