Work Step by Step

Write equivalent ratios where p is the unknown percent. Cross multiply to find p. $\frac{567}{756}=\frac{p}{100}\rightarrow$ cross multiply $756p=567\times100\rightarrow$ simplify $756p=56700\rightarrow$ divide both sides by 756 $\frac{756p}{756}=\frac{56700}{756}\rightarrow$ simplify $p=75$
