Question

4. Cindy's math test had 94 questions on it. Shegot 14 problems wrong, what percent of the problems did she get correct?

Answer 1

We can solve this question by means of the rule of three as follows:

`\begin{gathered} 94\text{questions ------ 100 \%} \\ 80\text{ correct answers ---- x} \end{gathered}`

then, x is given by

`x=(80*100)/(94)`

which gives x= 85.11. Then the answer is 85.11 %
