The ratio of boys to girls in Mrs. Reiter’s music class is 2 to 3. There are 24 girls in the class. ?

To find the total number of students in Mrs. Reiter's music class, first find the number of boys.

Since the ratio of boys to girls is 2 to 3, the ratio can be written as 2x:3x, where x is a multiplier.

We know that there are 24 girls in the class, so 3x = 24. Solving for x, we find that x = 8.

Therefore, the number of boys is 2x = 2(8) = 16.

The total number of students in Mrs. Reiter's music class is 24 girls + 16 boys = 40 students.

The correct answer is D) 40.
