Work Step by Step

Cross multiply to find percent. $\frac{percent}{100}=\frac{amount}{base}$ $\frac{p}{100}=\frac{\frac{11}{64}}{\frac{13}{32}}$ $\frac{13}{32}p=\frac{11}{64}\times100$ $\frac{13}{32}p\times\frac{32}{13}=\frac{11}{64}\times100\times\frac{32}{13}$ $\frac{13}{32}p\times\frac{32}{13}=\frac{11}{/\!\!\!32\times2}\times100\times\frac{/\!\!\!32}{13}$ $p=\frac{11}{26}\times100$ $p=42.3$
