Here,first we need to understand the meaning of the word "Rational". If we go by English definition,it is close to "logical/objective/specific/detailed ". So, why we are calling any number as logical/objective/specific/detailed. I think ,it is because we are trying to find out more about the numbers knowing the concepts of integers/decimals/fractions.If we think of a number (like 2) we call it a whole number/natural number but we do not know about the denominator of this number. So if we write it as 2/1 which makes it a fraction not changing the value, (only changing the representation), and hence RATIONAL (detailed/specific with a logic/detail that denominator is 1) and it becomes a more specifically-defined number. So, if we define a rational number, we can say it's about representation of the number and it is done in the form a/b and b is not equal to 0. Thus, all integers , all whole numbers ,all natural numbers are rational numbers.These must have terminating decimal point which means numbers should be expressible in the form of a fraction (otherwise the numbers then are called as irrational numbers).

A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers. The number 8 is a rational number because it can be written as the fraction 8/1.
