Question

Mandy gets 6 out of every 8 questions on a test correct. If she gets 27 questions correct, how many questions are on the test?

Answer 1

36

Explanation:

She gets 6 question right for every 8 question that means a ratio of 6/8 which is equal to 3/4

so we can say the ratio multiplied by the number of questions equals the correct answers

while x is the number of questions:

solve for x

3/4 * x = 27

x = 27 / (2/3) = 36
