Final answer:

To determine the total number of students in the class, set up a proportion where 36% equals 9 students and 100% equals the total number of students (x). Cross-multiply and divide to find that the total number of students in the class is 25.

Step-by-step explanation:

The student's question is how to determine the number of total students in a class if 36% voted for dodgeball and that represents 9 students.

To find the answer, use the concept of percentages. Since 36% represents 9 students, you can set up a proportion where 36% is to 9 students as 100% is to the total number of students in the class (x).

Setting up the proportion, it looks like this:

  • 36 / 100 = 9 / x

To solve for x, you can cross-multiply and divide:

  • 36x = 9 * 100
  • x = (9 * 100) / 36
  • x = 900 / 36
  • x = 25

Therefore, the total number of students in the class is 25.
