Question

Out of the 72 multiple choice questions on the sciencefinal exam, Paul correctly answered 58.5 of them. Whatis his score on his exam (as a percent)?

Answer 1

To solve the exercise you can use a rule of three, like this

$\begin{gathered} 72\text{ total questions}\rightarrow100\text{\% score} \\ 58.5\text{ questions answered correctly}\rightarrow x\text{ score} \\ x=\frac{58.5\cdot100\text{\%}}{72} \\ x=\frac{5850}{72}\text{\%} \\ x=81.25\text{\%} \end{gathered}$

Therefore, Paul's score on his exam iss 81.25%.
