Representation of rational numbers on the Number Line. Rational number between two rational numbers. Simply rational numbers can be defined as fractions that can be represented on the number line.

Let us look at the concepts that govern rational numbers. The properties we are going to discuss are basic mathematical properties that are applicable on integers as well.

Let us discuss the properties one by one:. Closure Property. The result of addition, multiplication and subtraction between any two rational numbers is also a rational number. This property is true for all mathematical properties except division because division by 0 is not defined.

So divisions other than 0 are included in the closure property. Commutative property. The commutative property is true only for addition and multiplication of rational numbers. For any two rational numbers:. Associative Property. Rational numbers follow the property of association only for addition and multiplication. Let a, b and c be three rational numbers:.

Distributive Property. Rational numbers follow distributive property for addition and multiplication only. For any three rational numbers p,q and r. Identity Property. The additive identity for any rational number is 0 and the multiplicative identity is 1. Inverse Property. Rational numbers can also be represented on the number line just like other whole numbers or integers.

Negative rational numbers are present to the left and the positive rational numbers are located on the right side of the number line. Representation of a rational number can be categorised into:. Proper Fraction: When the value of the numerator is less than the value of denominator, the fraction is called proper fraction and the value is less than one. Improper Fraction: In case of the improper fraction, the value of the numerator is greater than the value of the denominator.

First, we convert the given fraction into a mixed fraction to get a better picture of where the number exists on the number line. There are a total of five exercises in this chapter which provides an explanation for topics related to standard identities and their application to algebraic expressions.
