RD Sharma Solutions for Class 8 Chapter 1 “Rational Number”- In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number. Examples: • 1/2 is a rational number (1 divided by 2, or the ratio of 1 to 2) • 0.75 is a rational number (3/4). This chapter mainly deals with rational numbers, and their properties of addition of rational numbers, subtraction of rational numbers and its properties, simplification of expressions involving addition and subtraction of rational numbers, multiplication of rational numbers and its properties, division of rational numbers, representation of rational numbers on the number line, and rational numbers between two rational numbers are discussed.
