From the question it is given that,

Number of students in the class who are above average = \frac{1}{6}

Number of students in the class who are average = \frac{1}{4}

Number of students in the class who are below average = 1 – ( \frac{1}{6} + \frac{1}{4} )

= 1 –. \frac{(2+3)}{12}

=1-\frac{5}{12}=\frac{(12-5)}{12}=\frac{7}{12} students

So, the number of students in the class = 48

Then,

Number of students below average = \frac{7}{12} × 48

= 7 × 4

= 28 students

∴The number of students in the class who are below average is 28.
