Question

At a pet show, the ratio of dogs to cats is 4:3. if the number of cats is 45, find the number of dogs at the show.answer:

Answer 1

Dogs / cats : 4/3 = d / 45.....4 dogs to 3 cats = d dogs to 45 cats
cross multiply because this is a proportion
(3)(d) = (45)(4)
3d = 180
d = 180/3
d = 60
so when there is 45 cats, there is 60 dogs
