Answer 2

Answer: OPTION D

Explanation:

To solve this problem you must apply the proccedure shown below:

- Convert from 48 inches to foot. You know that 12 inches=1 foot. Then you have:

`(48inches)((1foot)/(12inches))=4feet`

- Therefore, keeping on mind that 48 inches is 4 feet, and you must find the ratio that correctly compares 2 feet to 48 inches, you can write:

`ratio=(2feet)/(4feet)`

- Reduce the fraction, then:

`ratio=(1)/(2)`

- You can rewrite it as following:

`ratio=1:2`
