Question

Use the number line. What fraction of 1 foot is 3 inches? What fraction of 1 yard is 3 inches?

Answer 1

1 foot----------------1/4

Explanation:

I yard----------------1/12

Answer 2

3 inches is
`(1)/(4)` of a foot

3 inches is
`(1)/(12)` of a yard

Explanation:

As shown on the number line, we know that 1 foot is equal to 12 inches. To find what fraction of a foot 3 inches is, we have to compare 3 inches to 12 inches.

Think: What do I have to multiply 12 by to get 3? If that's too difficult, think: what do I have to multiply 3 by to get 12?

You have to multiply 3 by 4 to get 12, so you have to multiply 12 by
`(1)/(4)` to get 3

A yard is 3 feet, and a foot is 12 inches. This means that a yard is 36 inches.

Do the same as above, and you will get
`(1)/(12)` as your answer.
