Answer
$\frac{909}{2000}$
Work Step by Step
$0.4545$ can be read as "four thousand, five hundred forty-five ten-thousandths," which helps us write the fraction: $\frac{4545}{10000}$. Additionally, 4545 is in the ten-thousandth's place value, meaning we need to put 4545 over 10,000.
Now, to finish our answer, we need to reduce. We can divide the numerator and the denominator by 5 to get our answer in simplest form:
$\frac{4545\div5}{10000\div5}$ = $\frac{909}{2000}$
