The first friend got 80% of the questions right on the test (96 out of 120).
If the second friend got the same percentage of questions right as the first friend, she would also get 80% of the questions right on her test.
Since the second friend took an exam with only 75 questions, she would get 80% of 75 questions right.
80% of 75 = 0.80 x 75 = 60
Therefore, the second friend would answer 60 questions correctly on her test.
