Choose the correct answer below.
A.
The number of dogs is 3.5 times the number of cats.
B.
Out of 7​ animals, 2 are cats.
C.
There are 5 more dogs than cats.
D.
The number of dogs divided by the number of cats is 2/7.

Answer 1

7/2 3.5 according to my calculations it’s A

Answer 2

The ratio of dogs to cats
7 to 2
Let’s look at the answers and cross out some of them

A seems valid, 7/2= 3.5

So B is wrong because 7 is the number of dogs not the number of total animals.

C is wrong because this is a ratio, and if the ratio is 7:2 then there could be 14:4 dogs and cats. 14 — 4 isn’t 5. We are not certain there are exactly this much dogs and this much cats.

D) For every 7 dogs there are 2 cats. 7/2 is dogs divided by cats, while 2/7 is cats divided by dogs

So the correct answer is A
