Question

A pet store sells puppies and kittens in the ratio 5:4.

If their sales of puppies and kittens combined came to 36, how many puppies did they sell?

Answer 1

Let us consider the ratio to be x

So, as per the question's statement, we can write it as;

`5x+4x=36`

`\implies 9x=36`

We will divide 9 on both the sides, we get;

`\implies x=(36)/(9) =4`

So, for getting the number of puppy sold we have to multiply it with 5, we get:

`5x=5*4=20`

They have sold 20 puppies.

Hence, the answer is
`20` puppies.

How do you calculate a ratio?

Divide data A by data B to find your ratio. In the example above, 5/10 = 0.5. Multiply by 100 if you want a percentage. If you want your ratio as a percentage, multiply the answer by 100.

How to simplify a ratio?

Ratios can be fully simplified just like fractions. To simplify a ratio, divide all of the numbers in the ratio by the same number until they cannot be divided any more.
