Answer: OPTION D

Step-by-step 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:

 [tex](48inches)(\frac{1foot}{12inches})=4feet[/tex]

- 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:

[tex]ratio=\frac{2feet}{4feet}[/tex]

- Reduce the fraction, then:

[tex]ratio=\frac{1}{2}[/tex]

- You can rewrite it as following:

[tex]ratio=1:2[/tex]
