The examples of numbers that are not natural are 8, 3.49, 0, etc.

Rational Number: Ratio of two integers where the denominator is not zero is called a rational number. One surprising fact is that a repeating decimal is also called a rational number. 

Ex:5/3, 16/7 these are rational numbers.

Irrational Number: An irrational number is a real number that cannot be written as a simple fraction. ‘’ is a very famous irrational number.

Decimals: Decimal is very interesting and fun part of the Number System. Decimal fractions were first introduced and used by Chinese at the end of the 4th century and then spread to the Middle East and from there to Europe. We use decimal in our daily life without our consciousness. For example – counting money, putting fuel into our vehicle or while measuring our weight. Decimals can never be whole numbers. Few example: 1.8, 000.23 etc.

Decimals classifications

Terminating decimal fractions are 17/4= 4.25, 21/5 = 4.2 and so on.

Non- terminating decimal fractions are 16/3 = 5.33333 , 15.35353535 etc.

Integer: All numbers which do not have a decimal in them are called integers. Thus, -9, 4, 1476 etc. Do you know? All integers are whole numbers including the negative numbers.

These are a few fundamental topics of the Number System. Class 9 Maths Chapter 1 will give you detailed explations of all of them with important exercises to practice in the NCERT Solutions for Class 9 Maths Chapter 1, exercise 1.3. Apart from this, you will get to know how to use these numbers in a logical manner to solve problems. There will be ‘n’ number of solved questions in the exercise 1.3 Class 9 Maths NCERT Solutions. These will help you have complete clarity on the subject.
