Number Systems — CBSE Class 9 Maths Worksheets

Rational and irrational numbers, their decimal expansions, and operations on real numbers.

Regular practice on Number Systems helps Class 9 students build confidence in Maths — short, focused worksheets reinforce what's taught in class far better than one long study session. Every worksheet is generated fresh with a matching answer key, so you can check your child's work without re-solving it yourself.

By the end of this chapter, students should be able to: Classify numbers as rational or irrational; Determine whether a rational number's decimal expansion terminates or repeats; Apply the laws of exponents to real numbers and rationalise denominators.
