The ratio of keepers to animals in the city zoo is 2 : 7. 12 keepers and 42 animals. If 21 more animals are added, how many total keepers are needed to maintain the ratio of keepers to animals?

A. 16

B. 17

C. 18

D. 19

E. 20

Answers

Answer:

C: 18

Step-by-step explanation:

All you have to do is write down the ratio. Then you find out that 21 is half of 42 so that means that the amount of zookeepers that you will have to add should be half the amount as well so instead of 12 it would be 6. Then you just add the two numbers together to get your final answer of 18.

The answer is 18 keepers

I'd say A, D, and B.

However, I would choose answers at a CONSTANT because, what if you need to divide or multiply or something, let's say Derek runs 5 miles per 1 hour, you'd have to divide. Yet, I recommend these three answers.
