Question

Mr. Smith's wife works at an animal hospital. There is a equivalent fraction relationship between the number of dogs and cats in the kennels. If there are 20 cats in the kennels, how many dogs?

Answer 1

Answer:

There are 10 dogs in the kennels

Step-by-step explanation:

The equivalent fraction relationship between the number of dogs and cats in the kennels is 1/2.

Which means, if $n_d$ the number of dods and $n_c$ is the number of cats, then,

$\frac {n_d}{n_c}=\frac{1}{2}\cdots(i)$

Given that there are 20 cats, so $n_c=20.$

Now, from equation (i) we have,

$\frac {n_d}{20}=\frac{1}{2}$

$\Rightarrow n_d=\frac{1}{2}\times 20$

$\Rightarrow n_d= 10$.

Hence, there are 10 dogs in the kennels.
