A rational number is a number which can be expressed in p/q form or as a ratio. Rational numbers can also be expressed as a fraction, in which “p” is the numerator and “q” is the denominator. The value of “q” should always be a whole number (non-zero denominators). Also, every integer is a rational number.

**Examples:**

- 4 is considered as a rational number since it can be expressed as 4/1.
- 5/3 is also considered as a rational number since it can be expressed as a fraction.
- A big number like 6633598,52594/25698 is also a rational number since it can be expressed as a fraction.
