Peter and Frank shot baskets. Each had 20 attempts. Peter scored thirteen and Frank scored twelve. Calculate each one's success rate as a percentage.

Final Answer:

a =  65 %
b =  60 %

Step-by-step explanation:

$$\begin{gathered} n=20 \\ a=100\cdot \frac{13}{n}=100\cdot \frac{13}{20}=\frac{100\cdot 13}{20}=\frac{1300}{20}=65\% \end{gathered}$$

$b=100\cdot \frac{12}{n}=100\cdot \frac{12}{20}=\frac{100\cdot 12}{20}=\frac{1200}{20}=60\%$
