In Mathematics, rational numbers can be defined as a type of real numbers. These numbers can be represented in the form of p/q where q is not equal to zero. Few examples of rational numbers can be listed as follows- 1/2, 3/4, ¼. The number zero is also a rational number since it can be represented in many forms such as 0/1, 0/2, 0/3, 0/4. Irrational numbers can be defined as those numbers that cannot be effectively represented as single fractions. These numbers cannot be depicted in the form of ratios, or as p/q where q is not equal to zero. Rational and irrational numbers are collectively referred to as Real Numbers within the number system. The number system along with details of the calculations involving the different types of numbers have been compiled in the ICSE Class 9 Mathematics Revision Notes Chapter 1.
