Answer
$140$
Work Step by Step
In the given problem, $P=49$ and $R=0.35.$ Using $P=BR$ or equivalently $B=\dfrac{P}{R},$ then
\begin{array}{l}\require{cancel}
B=\dfrac{P}{R}
\\\\
B=\dfrac{49}{0.35}
\\\\
B=\dfrac{\cancel7(7)}{\cancel7(0.05)}
\\\\
B=\dfrac{7}{.05}
\\\\
B=\dfrac{7}{.05}\cdot\dfrac{100}{100}
\\\\
B=\dfrac{700}{5}
\\\\
B=140
.\end{array}
