Question

A pet store sells puppies and kittens in the ratio 5 : 4 . If their sales of puppies and kittens combined came to 27, how many puppies did they sell?

Answer 1

Answer:

15 puppies

Step-by-step explanation:

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

As per the ratio, total puppies and kittens is 5+4= 9

If their sales of puppies and kittens combined came to 27

The ratio of puppies to the total is 5:9

LEt x be the puppies sold

RAtio of puppies sold to the total is x: 27

Now make a proportion using the ratio and solve for x

$\frac{5}{9} =\frac{x}{27}$

cross multiply it

$135=9x$

Divide both sides by 9

x=15

S, 15 puppies

Answer 2

So puppies will be 5x and Kittens 4 x so they combined will be 5x+4x=27
9x=27
X=3
