$\frac{1}{8}$, .125

Work Step by Step

We are given the percent 12.5%. We know that 12.5%=$12.5\div100=(12.5\times10)\div(100\times10)=\frac{125}{1000}=\frac{125\div125}{1000\div125}=\frac{1}{8}$ To write 12.5% as a decimal, divide by 100 and drop the percent sign. $12.5\div100=.125$ Therefore, $\frac{1}{8}=.125$=12.5%.
