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.
