Answer
$\frac{5}{8}$
Work Step by Step
We are given the decimal .625. In order to write this decimal as a fraction, we can divide .625 by 1 (which is equivalent to having .625 as the numerator and 1 as the denominator).
$.625\div1=\frac{.625}{1}$
Next, we multiply both the numerator and denominator by factors of 1 until both have no decimal points.
$\frac{.625}{1}=\frac{.625\times1000}{1\times1000}=\frac{625}{1000}$
Reduce to simplest form.
$\frac{625}{1000}=\frac{625\div125}{1000\div125}=\frac{5}{8}$
