Question

Ok 14. The ratio of cats to dogs in a

Is local animal shelter is 4:7. If
there are 28 cats, how many
dogs are at the shelter?

Answer 1

49 dogs

Explanation:

given that the ratio of cats : dogs is 4 : 7

which means that :

for every 4 cats, there are 7 dogs

if we express this as a unit rate, this also means that :

for every 1 cat, there are 7/4 dogs.

given that there are 28 cats, therefor the number of dogs

= number of cats x unit rate

= 28 x (7/4)

= 49 dogs

Answer 2

49 dogs

Explanation:

the 4 part of the ratio relates to 28 cats , then

28 ÷ 4 = 7 ← value of 1 part of the ratio , then

7 parts = 7 × 7 = 49 ← number of dogs at the shelter
