Answer
$70$%
Work Step by Step
In the given problem, $B=60$ and $P=42.$ Using $P=BR$ or equivalently $R=\dfrac{P}{B},$ then
\begin{array}{l}\require{cancel}
R=\dfrac{P}{B}
\\\\
R=\dfrac{42}{60}
\\\\
R=\dfrac{\cancel6(7)}{\cancel6(10)}
\\\\
R=\dfrac{7}{10}
\\\\
R=0.7
.\end{array}
The expression above is equivalent to 70%.
