NCERT Solutions for Class 7 maths Chapter 9 Rational Numbers

A rational number is a number that is expressed as the ratio of two integers in the form of p/q, where the denominator should not be equal to zero (q is not equal to zero). In contrast, an irrational number cannot be expressed in the form of fractions. Rational numbers are terminating decimals, but irrational numbers are non-terminating. Since q may be equal to 1, every integer is a rational number.
