We have to express the ratio "12 inches to 4 feet" in its simplest form.
We start by multiplying the fraction by "1 ft / 12 inches" and eliminate the units:
[tex]\frac{12\text{ in}}{4\text{ ft}}\cdot\frac{1\text{ ft}}{12\text{ in}}=\frac{12\cdot1}{4\cdot12}=\frac{1}{4}[/tex]We then get the ratio in its simplest form: 1 to 4.
Answer: the ratio is equal to 1:4.
If we want to write it as a fraction, it is equivalent to 1/4.
