Answer:
Step-by-step explanation:
The total number of people taking the test was 36
The total of pass / fail in the ratio was 7 + 5 = 12
The ratio of those failing was 5/12
So the number failing was = total * (failing / ratio / total)
Number failing = 36 * 5/12
Number failing = 180 / 12
Number failing = 15
The number of students who failed was 15.
