FAQs on RD Sharma Class 10 Solutions Chapter 1 - Real Numbers (Ex 1.3) Exercise 1.3
1. What are some properties of Irrational Numbers?
The numbers which cannot be denoted in a fractional form (p/q) are called Irrational Numbers. Some properties of irrational numbers are- They consist of both, non-terminating and non-recurring decimals.
Irrational Numbers are real numbers
When an irrational and a rational number are added, their sum is always an irrational number only.
When any of the irrational numbers are multiplied by any non-zero rational number, their product is always an irrational number.
For any two given irrational numbers, their Least Common Multiple (LCM) may not exist.
The addition, multiplication, subtraction, and division of two irrational numbers may or may not be a rational number.
2. Is 0 both a whole number and a natural number?
0 is a whole number but not a Natural Number. In the number system, Natural numbers are described to all the positive integers from 1 to infinity. Natural numbers are also known as counting numbers as they do not include zero or negative numbers. While on the other hand, Whole Numbers are natural numbers, but with a 0. The only difference between Whole Numbers and Natural Numbers is that Whole Numbers contain 0 and Natural Numbers do not.
3. What is the difference between Integers and Real Numbers?
The major difference between real numbers and integers is that integers are real numbers but real numbers are not integers. Real numbers include number sets such as rational numbers, whole numbers, natural numbers, and irrational numbers whole Integers include positive numbers, zero, and negative numbers. Real numbers are represented by the letter 'R' while integers are represented by the letter 'Z'. On a number line, every point depicts a unique real number while only whole numbers and negative numbers denote integers on a number line. These are the major differences between integers and Real numbers.
4. How to study Class 10 real numbers for full marks?
To get full marks in any subject, the students have to do plenty of practice. Especially in maths where the question paper is full of numerical questions.

Step 1: Draw one horizontal line with arrows on both ends. Then mark the number 0 in the middle and 0 is called the origin.
Step 2: Mark equal lengths on both sides of the origin and label them with a definite scale.
Step 3: The student should mark positive numbers lying on the right side of the origin and the negative numbers lying on the left side of the origin.
This is how a student can represent Real Numbers on a number line.
