For most people even those who are familiar with mathematics, it becomes sometimes difficult to comprehend what exactly is a rational number and how it is different from its counterpart that is irrational numbers. While explaining this concept, we’ll answer with examples to make the understanding easier. Furthermore, the answer Is 6 Rational Number?
What are rational numbers?
Let’s first understand the underlying criteria to distinguish rational numbers. Numbers such as 2/7, 8/3, or 12/2 which can be explained by whole numbers are considered rational numbers. They are called rational numbers and these can also be expressed by fractions. A denominator is always a natural number and the numerator is always a positive integer.

There is no concept of division in natural numbers. It is not possible to divide a natural number by another natural number. But it is possible when we use the concept of rational numbers. Let us take an example, if we want to express the number 6/2 then the easiest way is to divide both the sides with a natural number, let us say we will divide the sides with 3 then it will become 3/6 which is equal to 1/2. But we cannot directly divide 2 with 6 as it is a fraction. So, we have to convert it into a rational number like 2/6.
