there are 12 questions

I got 7 right

the easiest way to solve this is by using a rule of three

Step 1

Let


12\text{ questiones }\Rightarrow100\text{ percent}

then


7\text{ questions }\Rightarrow x\text{ percent}

Step 2

do the relation and solver for x


\begin{gathered} (12)/(100)=(7)/(x) \\ 12\cdot x=100\cdot7 \\ 12\cdot x=700 \\ x=(700)/(12) \\ x=58.33 \\ \end{gathered}

so, you did the 58.33 %
