RS AggarwalSolutions for Class 7 Maths Chapter 4 Rational Numbers
In mathematics, a “Rational Numbers” 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. Every integer is a rational number. Rational Numbers are numbers that we are familiar with – natural numbers, whole numbers and integers. Natural numbers start with 1 and go on endlessly up to infinity. If we add 0 in these sets of numbers, then those numbers become whole numbers. Now in these sets, if we further add the negative numbers, then we call them integers. We also use rational numbers in our daily life. We shall recall them here and extend our ideas to rational numbers like positive rational numbers, negative rational numbers, standard form of rational number, representation of rational numbers on the real line, comparison of rational numbers. And the addition of rational numbers, subtraction of rational numbers, multiplication of rational numbers, and division of rational numbers.
