Question

I need to know the answer, and how you got it, please help thanks

Answer 1

For this question, a quick way of knowing the answer is by a unit analysis, if we want to obtain inches from feet, then we have to divide by foot and multiply by inches:

`\frac{\text{feet}}{\text{foot}}*\text{inches.}`

Now, the above expression is the same as:

`\text{feet}*(inches)/(foot)\text{.}`

Answer: Last option, we have to multiply by:

`\frac{12\text{ inches}}{1\text{ foot}}.`
