## FAQs on RD Sharma Solutions for Class 10 Maths Chapter 1 - Real Numbers

**1. What is a real number according to RD Sharma class 10 Maths?**

A real number is a value of a continuous quantity that can represent a distance along a line. It is a value we use to quantify things. An integer on the other hand includes a whole number without a decimal point that is either positive integers (1, 2, 3...) or negative integers (-1,-2,-3...). Numbers that include decimal points (3.14) or fractions (5/7) do not count as being whole numbers but can be considered as real numbers.

**2. What is the use of real numbers?**

Real numbers are widely used in geometry to measure lengths, breadths, and depths. Along with distance measurement, they are also used to measure other quantities like mass, time, speed, energy and many more. For example, your room has a length of 10 feet (3.048 m), a breadth of 10 feet (3.048 m), and a depth of 5 feet (1.524 m). These measurements are represented in real numbers.

**3. According to RD Sharma class 10 Maths, what is an irrational number?**

A term that is used to describe any real value that cannot be written as a ratio of two whole numbers is known as an irrational number. For example, π (3.141 592...) is an irrational number since it cannot be written as the ratio of one whole number to another (e.g., not 3/11). A rational number on the other hand can always be written as exactly two whole numbers divided by each other, like 1/10 or 43/99.
