Step 1:
List all the number of courses
22 , 17 , 11 , 9 , 21 , 14 , 19 , 25 , 5, 12 , 7 , 16
Step 2
List number fewer than 11
9, 5, 7
Number of courses fewer than 11 = 3
Step 3:
The percentage of these students who have taken fewer than 11 courses
[tex]\begin{gathered} =\text{ }\frac{3}{12}\text{ }\times\text{ 100\%} \\ =\text{ }\frac{300\text{ \%}}{12} \\ =\text{ 25 \%} \end{gathered}[/tex]
Final answer
The percentage of these students who have taken fewer than 11 courses
= 25%
