Question

Miss Clark farm has chickens and pigs. There are a total 26 animal feet and 8 animal heads on her farm. If 20 feet belong to the pigs and 6 feet belong to the chickens, the ratio of the number of pigs to the number of chickens is

Answer 1

5 pigs: 3 chickens

pigs have four feet, so if 20 feet belong to the pigs, there's 5 pigs, because 5x4=20.
chickens have 2 feet, so if 6 feet belong to the chickens, there's 3 chickens, because 2x3=6.

Answer 2

There will be 5:3 because pigs have 4 feet each so divide 4 from 20 to get 5, then you divide 2 from 6 because chickens have 2 feet so you put the ratio in order to get 5:3
