Question

If Wendy answered 14 questions correctly and obtained 70%, how many questions were on the test?questions

Answer 1

Let x be the total number of questions on the test; then,

`\begin{gathered} 14\to70\% \\ x\to100\% \end{gathered}`

Which is equivalent to

`\Rightarrow(14)/(70)=(x)/(100)`

Solve for x as shown below

`\begin{gathered} \Rightarrow x=(14\cdot100)/(70)=20 \\ \Rightarrow x=20 \end{gathered}`

The answer is 20 questions in total on the test
