Step-by-step explanation:
From the question it is given that, Number of students in the class are above average = 1/6 Number of students in the class are average = ¼ Number of students in the class are below average = 1 – ((1/6) + (¼)) = 1 – ((2 + 3)/12) = 1 – (5/12) = (12 – 5)/12 = 7/12 students. So, the number of students in the class = 48 Then, Number of students below average = (7/12) × 48 = (7/1) × 4 = 28 students
