The first week of January there are 49 dogs and 28 cats in an animal shelter. Throughout the month the ratio of dogs to cats rem

Rudiy27

Answer:

Step-by-step explanation:

If the ratio of dogs to cats is 49:28, as an actual ratio (fraction), this is

$\frac{d}{c}:\frac{49}{28}$

We can reduce that to make the numbers smaller without changing the ratio. reducing gives us

$\frac{d}{c}:\frac{7}{4}$

We will use that ratio now to set up a proportion that involves a given number of cats and an unknown number of dogs. Keeping dogs on top and cats on bottom,

$\frac{d}{c}:\frac{7}{4}=\frac{x}{20}$

Cross multiply to get

4x = 140 so

x = 35

According to the ratio of dogs to cats, if there are 20 cats, there will be 35 dogs.
