Answer

$\frac{5}{8}$, 62.5%

Work Step by Step

We are given the decimal .625. To write .625 as a percentage, we must multiply by 100 and attach a percent sign to the end. $.625=(.625\times100)$%=62.5% 62.5%=$62.5\div100=(62.5\times10)\div(100\times10)=\frac{625}{1000}=\frac{625\div125}{1000\div125}=\frac{5}{8}$ Therefore, $\frac{5}{8}=.625$=62.5%
