Before you understand this concept, you are advice to read: What is Ratio ? What are Integers ? Definition: The word ‘rational' has been derived from the word ratio . We know that ratio is written as p:q and it can also be written in the form of fraction i.e. p/q where both p & q are natural numbers and q is not equal to zero. And when ratio of integers is be written in the form of p/q, where both where both p & q are integers and q is not equal to Zero, it's called Rational Number In other words, a rational is a number which can be expressed in the form of p/q , where both p & q are integers and q is not equal to zero Few examples of rational numbers are 5/7, -8/13, 23/-7, -46/-11 Following are the other concepts which you can study from above respective links: What are Equivalent Rational Numbers ?
