Question

A farmer has the same number of chickens, cows and goats. Together, all these animals have 210 legs. How many chickens live on this farm?

Answer 1

Since he has an equal amount of animals you should divide the total number of animals by what animals he has

210\3=70 animals of each

So 70 chicken I hope this helped

Answer 2

21

Explanation:

Chickens - 2x

cows - 4x

goats = 4x

2x+4x+4x+210

10x=210

x=21

CHECK:

21 chickens = 42 legs

21 cows = 84 legs

21 goats = 84 legs

42+84+84=210 legs
