RS Aggarwal Solutions Class 7 Maths Chapter 4 – Rational Numbers

## RS Aggarwal Solutions Class 7 Maths Chapter 4 Rational Numbers – Overview

**Rational Number**

A number that can be expressed in the form of p/q where q ≠ 0 is called a rational number. Eg: 1/3, 50/34, 72/99, etc. A rational number can be positive, negative, and zero as well as expressed in the form of a fraction. Hence, all the whole numbers are rational numbers.

**Properties Of Rational Numbers**

- Closure Property: A+B=B+A

A*B=B*A

- Associative Property: A+(B+C)=(A+B)+C

(A*B)*C= A*(B*C)

- Distributive Property: A*(B+C)=A*B+A*C

**Standard Form Of Rational Numbers**

When the denominators and numerators of a rational number have only a common factor of 1, it is said to be standard.

For example; 24/120, a rational number with the numerator and denominator are 24 and 120 respectively, have more than 1 common factor. When 24/48 is simplified, we get ½ which is in standard form. ½ is in standard form since 1 and 2 have no common factor other than 1.

**Difference b/w Positive & Negative Rational Numbers**

Positive Rational Numbers |
Negative Rational Numbers |

Definition: A Rational number is said to be positive if both the numerator and denominator have the same signs. Examples: 13/72, 1/4, 25/50 |
Definition: A Rational number is said to be negative if the numerator and denominator have opposite signs. Examples : -13/72 , -1/4 , -25/50 |

Range: Greater than 0 |
Range: Less than 0 |

**Multiplicative Inverse Of Rational Numbers**

The multiplicative inverse of a rational number is the reciprocal of a given rational number. So, the multiplication of the rational number and the multiplicative inverse should always be equal to 1.

**Additive Inverse Of Rational Numbers**

The additive inverse of a rational number is the number when added to the rational number gives a zero. So, the additive inverse of a rational number is negative of that rational number.

**Difference b/w Rational and Irrational Numbers**

Rational Numbers |
Irrational Numbers |

Definition: A rational number is defined as a number that can be expressed in the form of p/q where q ≠ 0. |
Definition: A rational number is defined as a number that cannot be expressed in the form of p/q. |

It includes only the decimals that are finite and are recurring. |
It includes the number that is non-terminating or non-recurring. |

Example: 10/13, 1.4444, 1.12346…. |
Example: √ 55, √ 5, √ 34 |
