$\frac{33}{80}$
Work Step by Step
We can write the given ratio as a fraction and then simplify in lowest terms.
$\frac{4\frac{1}{8}inches}{10inches}$
Since both the denominator and numerator have the same unit, we can divide out the common unit.
$\frac{4\frac{1}{8}}{10}=\frac{\frac{33}{8}}{10}=\frac{33}{8}\times\frac{1}{10}=\frac{33}{80}$
