Solution
Total number of students in Class A = 25
Students passed in first class in Class A = 20
Hence, fraction = `20/25`
= `4/5`
Total number of students in Class B = 30
Students passed in first class in Class B = 24
Hence, fraction = `24/30`
= `4/5`
∴ An equal fraction of students passed in first class in both classes.
