Write any three rational numbers.

Hint: To give an answer to this question first we need to know about the rational numbers. Rational numbers are those numbers which can be represented in the form of $ \dfrac{p}{q} $ where p and q are integers and q is not equal to zero. We will use this concept to give the answer.

Complete step by step answer:
We have to write three rational numbers.
We know that numbers which are represented in the form of $ \dfrac{p}{q} $ where p and q are integers and q is not equal to zero are known as rational numbers. Rational numbers can be positive or negative. In a standard rational number, a denominator is always greater than zero. Rational numbers include numbers that are finite and periodic in nature. Every whole number on the number line is a rational number because we can express it in the form of $ \dfrac{p}{q} $. We can perform any mathematical operation like addition, subtraction, multiplication, and division on rational numbers. We can write any decimal number which is finite in the form of a rational number.
So, we can write three rational numbers as $ \dfrac{2}{3},\dfrac{1}{3},\dfrac{3}{5} $
Also we can give three negative rational numbers as $ \dfrac{-1}{2},\dfrac{-1}{3},\dfrac{-3}{5} $

Note:
To solve these questions students must remember the definition and properties of rational numbers. Perfect squares are always rational numbers. $ \sqrt{2},\sqrt{3} $ are examples of irrational numbers. Numbers that are non-terminating and non-repeating come under the category of irrational numbers.
