In this Class 9 Mathematics topic from the Number Systems chapter, students explore rational numbers as numbers that can be written in the form p/q, where p and q are integers and q is not zero. They learn to represent and compare them on the number line, identify equivalent forms, and perform addition, subtraction, multiplication, and division. The topic also develops understanding of properties such as closure, commutativity, associativity, and distributivity, helping students apply rational numbers accurately in mathematical problems.
