Answer:
A. 36/42
Step-by-step explanation:
What do you multiply 7 by to get 42?
6. That is what the denominator was multiplied by, and so, the equivalent fraction must have a numerator that is 6 times larger than the original.

A. 36/42
Consider that 100%-72%=28% represents the percentage of wrong answers. I would think as fractions as:
if 100% is the total number of answers and 28% are the wrong ones
as
if x is the total you have 14 wrong you can write:

x=(100/28)*14=50 questions
