In this class of 4/5 students are right handed. if there are 20 right handed students, what is the total number of students in this class?

Let x be the total number of students in the class. We have:
4/5x = 20

Cross multiplying or using our equation calculator, we get:
4x = 100

Divide each side by 4
x = 25
