nots of rational numbers of class 8
Answers
Basically we'll learn first what is the exact meaning of Rational number?
numbers which are involved in many mathematical applications such as addition, subtraction and multiplication which are inherently closed with many mathematical processes are called Rational numbers
Now, Natural numbers are set of numbers starting from 1 counting up to infinity. The set of natural numbers is denoted as ′N′.Whole numbers are set of numbers starting from 0 and going up to infinity. So basically they are natural numbers with the zero added to the set. The set of whole numbers is denoted as ′W′Closure Property Closure property is applicable for whole numbers in the case of addition and multiplication while it isn’t in the case for subtraction and division. This applies to natural numbers as well. Commutative Property Commutative property applies for whole numbers and natural numbers in the case of addition and multiplication but not in the case of subtraction and division. Associative Property Associative property applies for whole numbers and natural numbers in the case of addition and multiplication but not in the case of subtraction and division.

Motivation- Work with a plan so that you are able to cover up your syllabus..
I know that there is no need to give motivation but if you are reading this and understanding these notes carefully so I thought this will make you motivate..
ok continue reading
rational number is a number that can be represented as a fraction of two integers in the form of p/q, where q must be non-zero. The set of rational numebrs is denoted as Q.
Distributive Property of Rational Numbers
Property of Rational NumbersGiven three rational numbers a,b and c, the distributivity of multiplication over addition and subtraction is respectively given as : a(b+c)=ab+aca(b−c)=ab−ac
Now the very main topic is
Representation of Rational Numbers on the Number Line..
Step 1 : Divide the distance between two consecutive integers into ‘n′ parts.
Step 1 : Divide the distance between two consecutive integers into ‘n′ parts.For example : If we are given a rational number 23, we divide the space between 0 and 1, 1 and 2 etc. into three parts.
Step 2: Label the rational numbers till the range includes the number you need to mark

Thank you so much and all the best
and if you are thinking that these are sufficient for your exam so let me tell you the answer is no this is not sufficient for your exam you have to study more!! there are some topics that I haven't mentioned it!!!!
Heyy i know this is so long but do it
