At a farm the ratio of cows to horses was 9:2 if there were 72 cows out of farm how many horses were there

Question

it would be helpful if it were by step by step so that I could understand it better to actually learn the concept

Answer 1

h = number of horses

c = number of cows

c/h = 9/2 ⇒

h = (2/9)c

If c = 72, then

h = (2/9)(72) = 16

Test the answer: c/h = 72/16 = 4.5 = 9/2
