$\frac{7}{8}$, .875

Work Step by Step

We are given the percent 87.5%. We know that 87.5%=$87.5\div100=(87.5\times10)\div(100\times10)=\frac{875}{1000}=\frac{875\div125}{1000\div125}=\frac{7}{8}$ To write 87.5% as a decimal, divide by 100 and drop the percent sign. $87.5\div100=.875$ Therefore, $\frac{7}{8}=.875$=87.5%.
