Question

10. A parking lot has 500 cars parked in it. 300 of the cars are black, 150 are

white, 25 are silver, and 25 are red. What is the ratio of red cars to black
cars to white cars to silver cars?
A. 1: 12: 6:1
B. 1: 6:12:1
C. 1: 5:9:1
D. 1:9: 5:1

Answer 1

A. 1: 12: 6:1

Explanation:

The lowest number is 25, so we assign it as 1.

300 is 25 times 12.

150 is 25 time 6.

25 is 25 time 1.

We originally have 25:300:150:25, if we were ordering the given numbers in the order they were asked to be in.

We have to change these numbers to their new form to make the ratio.

25 → 1

300 → 12

150 → 6

25 → 1

That's how we end up with 1:12:6:1
