Question

Paul's car is 13 feet long. He is making a model of his car that is 1/7 the actual size. What is the length of the model?

A.
13/7 feet
B.
7/13 feet
C.
14/65 feet
D.
21/52 feet

Answer 1

The right choice is A. 13/7 feet

Explanation:

Since the actual size 13 feet

And the size of model is 1/7 of the actual size

So

The model size will be

= 1/7 (Original size)

= 1/7 * 13

= 13/7

Answer 2

A. 13/7 feet

Explanation:

This is because the length would be 1/7th of 13 feet. That is the 1/7th portion a total of 13 which is obtained by multiplying the fraction by the number to be divided (the actual value of the car)

So in this case, we multiply 13 by 1/7

13 x 1 / 7

= 13/7

Other example for clarity

For instance, if we were making 1/5th the size of the actual model, we would be multiplying 1/5 with the actual value 13 :

13 x 1/5 = 13 / 5

Hope this helps!
