Question

A farmer has 45 chickens and rabbits. There are 140 legs all together . How many chickens do the farmer has? How many rabbits does a farmer have

Answer 1

• 20 chickens
• 25 rabbits

Explanation:

Let r represent the number of rabbits the farmer has. Then 45-r is the number of chickens. The total number of legs is then ...

4r +2(45-r) = 140

r +45 = 70 . . . . . . . . divide by 2 and simplify

r = 25 . . . . . . . . . the number of rabbits

45 -r = 20 . . . . . the number of chickens

The farmer has 20 chickens, and 25 rabbits.
