In a class A of 25 students, 20 passed in first class; in another class B of 30 students, 24 passed in first class. In which class was a greater fraction of students getting first class?

Explanation

To solve the problem step by step, we need to find the fraction of students who passed in first class for both classes A and B, and then compare these fractions.

### Step 1: Determine the fraction of students in Class A who passed in first class.
- Class A has 25 students, and 20 of them passed in first class.
- The fraction of students who passed in first class in Class A is given by:
\[ \text{Fraction for Class A} = \frac{20}{25} \]
