Question 17

Explanation

To determine which class has the highest percentage of students who like mathematics, we use the same proportion formula as in the previous question, comparing the number of students who like the subject to the total number of students in that class.

Based on the comparison above, class $\text{NNN}$ has the highest percentage at $47.3\%$. This indicates that the proportion of students who like mathematics in that class is greater than in the other classes.
