Answer

$\frac{3}{8}$

Work Step by Step

We can write the given ratio as a fraction and then simplify in lowest terms. Since 1 foot has 12 inches, we can write 2 feet as $(2\times12)=24$ inches. $\frac{9 inches}{24 inches}$ Since both the denominator and numerator have the same unit, we can divide out the common unit. $\frac{9}{24}=\frac{9\div3}{24\div3}=\frac{3}{8}$
