Answer 1

If 32 students are enrolled in the course, there would be 24 girls.

Explanation:

Given that For every boy in an advanced math course there are 3 girls who are taking the course.

It means if there are four students in the class. There would be 3 girls and 1 boy. Thus, 75% of the students are girls.

Given that there are 32 students enrolled in the course.

so

75% of 32 = 75/100 × 32

= 24

Thus, if 32 students are enrolled in the course, there would be 24 girls.
