Question

Of the 75% of a group that passed a physical examination only 3/5 passed the additional psychological exam. What fraction of the group passed both exams

Answer 1

To find the fraction of the grouo that passed both exams, we need to first convert 75% into a fraction:

75%
=75/100
=3/4

We can then mutiply the fraction above by the students who passed the psychological exam:

3/4×3/5
=9/20

Therefore the answer is 9/20.
