On a test, 86% of the questions are answered correctly. If 215 questions are correct, how many questions are on the test?

1 answer:

7 0

The text tells us 215 is 86% of the questions
We are looking for 100% of the questions

We get that number by:
Multiplying 100 and 215 and dividing it by 86

$\frac{100 \times 215}{86}$
