if 7 students make up 20% of the class, how many students are there total in the class?

Let's assume there are x total students in the class.

If 7 students make up 20% of the class, it means 7 = 0.2x (since 20% is equal to 0.2)
Dividing both sides of the equation by 0.2, we get:
7 / 0.2 = x
Simplifying, we find that x = 35.
Therefore, there are a total of 35 students in the class.
