The rate is unknown. The base is $\frac{1}{8}$, the number following "of". The part is the other number, $\frac{1}{15}$. $R=\frac{P}{B}=\frac{\frac{1}{15}}{\frac{1}{8}}=\frac{1}{15}\times8=\frac{8}{15}=0.5\overline3$ Move the decimal two places to the right to convert the decimal to a percent. Round to the nearest tenth. $0.5\overline3\approx53.3\%$
