Answer 1

Option:

a. for every 13 dogs, there are 25 cats.

b. there are twice as many cats as dogs at the shelter.

c. the shelter has more dogs than cats.

d. there are 25 animals in the shelter.

Answer:

a. for every 13 dogs, there are 25 cats.

Explanation:

Represent Dogs with D and Cats with C;

So;

`(D)/(C) = (13)/(25)`

By comparison:

`D=13`

`C = 25`

This implies that:

For every 13 D, there are 25 C

Hence: Option A is true
