Question

Guys please help me...

On a farm there are chickens, ducks and pigs.
The ratio of the number of chickens to the number of ducks is 7:2
The ratio of the number of ducks to the number of pigs is 5:9
There are 36 pigs on the farm.
Work out the number of chickens on the farm.​

Answer 1

On the farm there are 70 chickens.

Step-by-step 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 *
  `(5Ducks)/(9Pigs)` = 20 ducks

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

• 20 ducks *
  `(7Chickens)/(2Ducks)` = 70 chickens

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