Work Step by Step

We are given the fraction $\frac{8}{100}$. We know that $\frac{8}{100}=8\div100=.08$ To write $\frac{8}{100}$ as a percentage, we can set $\frac{8}{100}$ equal to $\frac{p}{100}$ (where p is the percentage representation of the given fraction) and take the cross products to solve for p. $\frac{8}{100}=\frac{p}{100}$ $8\times100=100\times p$ $800=100p$ Divide both sides by 100. $p=8$% Therefore, $\frac{8}{100}=.08=8$%.
