How do we compare classes in such cases?
Let us say we have 2 classes A and B
Class A
10 Sport lovers
20 Art lovers
🧘
Class B
8 Sport lovers
8 Art lovers
⛹️♂️
If you are a sports lover which class would you rather be in?
There are many ways of comparing quantities. Let us see what some of the other students that picked class B said.

🧓
Class A has 10 sports lovers out of 30 students, which is 1 out of 3. Class B is 1 out of 2. So, I stand a better chance.
