Answer:

On the farm there are 70 chickens.

Explanation:

We can directly work out the number of ducks from the given number of pigs, with the ratio of ducks to pigs:

  • 36 pigs * [tex]\frac{5Ducks}{9Pigs}[/tex] = 20 ducks

Then we work out the number of chickens, using the ration of chickens to ducks:

  • 20 ducks * [tex]\frac{7Chickens}{2Ducks}[/tex] = 70 chickens

If on the farm there are 36 pigs, there are 70 chickens as well.
