The ratio of roosters to chickens is 2 to 8. If there are 5 roosters, how many chickens are there?
Aloiza [94]
Roosters to chickens is 2 to 8

That means where there are 2 roosters, there are 8 chickens.

Simplify the ratio 2:8
The ratio can be simplified to 1:4

So, for 1 rooster, there are 4 chickens.

Now, the question says that if there are 5 roosters, how many chickens will there be?

1 rooster to 4 chickens
5 roosters to ? chickens

We went from 1 rooster to 5 rooster. We multiplied by 5.
To find out how many chickens there are for 5 roosters, multiply 4 chickens by 5.

4 * 5 = 20

Where there are 5 roosters, there will be 20 chickens.

Another way to solve is as follows:

\frac{2}{8} =\frac{5}{x}\\\\\sf{Cross~multiply}\\\\2x = 5\times 8\\\\2x = 40\\\\x = 20\\\\\boxed{\bf{x=20}}

Your final answer is 20 chickens.<span />
