In class 5, 1/2 of the class got a high score, 1/3 of the class got an average score and 7 students got below the average score. How many students were there

Answer 1

1 - (1/2 + 1/3) = 1 - (3/6 + 2/6) = 1 - 5/6 = 1/6

So, 7 is 1/6 of the total number of students.

(1/6)s = 7

6(1/6)s = 7(6)

s = 42 students total
