Answer : Equal fraction of students passed first class.
Solution :
Fraction of students passing first class for class A = 20 / 25 = (4 / 5)
Fraction of students passing first class for class B = 24 / 30 = (4 / 5)
Since both fractions are equal, equal fraction of students passed first class

For class A:
Total students=25
Students passed with first class=20
So fraction of students in class A who passed with first class = students passed with first class/total students
Therefore ,Fraction=20/25=4/5
For class B:
Total Students=30
Students passed with first class=24
So fraction of students in class A who passed with first class = students passed with first class/total students
Therefore ,Fraction=24/30=4/5
Hence the both classes have equal fraction of those students who passed with first class.

According to the question there are two classes, class A and class B consisting of 25 and 30 students respectively out of which 20 students from class A passed in First class and 24 students from class B passed in First class.
The Fraction is the ratio of objects or entity to the total number of object or entity present.
for example,
There are 5 bananas out of which a person buys 2 bananas, the the fraction of bananas consumed by the buyer is 2/5.
therefore,
The ratio of students from class A passed in First class = 20/25 = 4/5
therefore, 4/5 fraction of students from class A passed in First class.
therefore,
The ratio of students from class B passed in First class = 24/30 = 4/5
therefore, 4/5 fraction of students from class B passed in First class.
fraction of students from class A passed in First class= fraction of students in class B passed in First class= 4/5.
Hence, in both the classes the fraction of students passed in First class is equal and not greater or lesser than any of the class.
