Question

Charlin got 15 questions correct on her exam and scored a 75%. How many (total) questions were on the exam?

Answer 1

Answer:

There were 20 total questions.

Step-by-step explanation:

$75\% = 0.75 = \frac{3}{4} \\ \frac{15}{ \frac{3}{4} } = \frac{15(4)}{3} = \frac{5 \times 3 \times 4}{3} = 5 \times 4 = 20$
