The subtopics that are Cbse Class 8 Maths Byjus You covered in the detail in the chapter are:. Properties of Rational Numbers. Representation of Cbse Class 8 Maths Byjus You Cbse Class 8 Maths Byjus You Cbse Class 8 Maths Byjus You rational numbers on the Number Line.
Rational number between two rational numbers. Simply rational Cbse Class 8 Maths Byjus You 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 Cbse Class 8 Maths Byjus You 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 Cbse Class 8 Maths Byjus You 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 Cbse Class 8 Maths Byjus You 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 Class Maths Cbse 8 Byjus You 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 Cbse Class 8 Maths Byjus You Cbse Class 8 Maths Byjus You than one. Improper Fraction: In case of the improper fraction, the value of the Maths You Byjus 8 Cbse Class numerator is greater than the value of the denominator.
First, we convert the given fraction Cbse Class 8 Maths Byjus You Cbse Class 8 Maths Byjus You into a mixed fraction to get a better picture of where the number exists on the number line. To represent the rational number we divide the distance between the two whole numbers into the number of subunits denoted by the denominator.
The number can also be represented using the process of successive magnification where we convert the rational number into decimal expansion and represent the decimal places successively.
The different Cbse Class 8 Maths Byjus You methods using which rational numbers between two rational numbers can be found are:. The basic Cbse Class 8 Maths Byjus You method that is used to find the number between two rational numbers is dividing their sum by 2. A rational number between 5 and 6 can be calculated Cbse Class 8 Maths Byjus You by. For numbers with a common denominator, rational numbers between them can be easily Cbse Class 8 Maths Byjus You found.
In the case of different denominators, the first step is to make the denominators of the fraction similar before finding the rational numbers between them. The pdf class 8 maths chapter 1 important questions contains different types of questions that cover all the sub-topics of the entire chapter. Important questions from each topic are included in Cbse Class 8 Maths Byjus You the pdf to give the students a clear and logical understanding of the chapter.
Some of the important questions that are commonly asked in the examination from this chapter are:. Find the rational number between 7 and 8.
Find the other number. Define the associative property for addition. What are whole numbers and natural numbers?
Explain the properties of rational numbers using examples. Represent 0. Find the additive and multiplicative inverse of Differentiate between rational and irrational numbers.
