What is the ratio of the length of the car to the length of the model?

Question

A model is made of a car. The car is 9 feet long and the model is 6 inches long. What is the ratio of the length of the car to the length of the model?

 

A) 18:1

B) 1:18

C) 9:6

D) 6:9

I think the answer is C) 9:6. Am I correct?

Answer 1

No you are wrong. 9 is in feet and 6 is in inches so they are not comparable. You can convert 9 feet to inches and you get 108. then the ratio is108:6, which can be reduced to 18:1. simply divide bot parts by 6.
