RATIONAL NUMBERS Rational Numbers1 - NCERT

RATIONAL NUMBERS IntroductionIn Mathematics, we frequently come across simple equations to be solved. For example,the equationx + 2 =13(1)is solved when x = 11, because this value of x satisfies the given equation. The solution11 is a natural number . On the other hand, for the equationx + 5 =5(2)the solution gives the whole number 0 (zero). If we consider only natural NUMBERS ,equation (2) cannot be solved. To solve equations like (2), we added the number zero tothe collection of natural NUMBERS and obtained the whole NUMBERS .
