Question

A model is made of a car. The car is 10 feet long and the model is 7 inches long. What is the ratio of the length of the car to the length of the model? A. 10 : 7 B. 7 : 120 C. 120 : 7 D. 7 : 10

Answer 1

1 foot is 12 inches,


The real length of the car which is 10 feet, that equals to 10*12in=120 in, is represented by 7 inches in the model.

Thus 120 inches in reality, are represented by 7 inches in the model.


We describe this ratio by 7:120 (the value in reality comes second).


Answer : B 7:120
