# Identify the following as rational or irrational numbers. Give the decimal representation of rational numbers:(i) (ii) 3 (iii) (iv) (v) (vi) (i) = 2 =  can be written in the form of , so it is a rational number.

Its decimal expansion is 2.0

(ii) 3 = 3 = 3 * 3 = 9 Since, the product of a rational and an irrational is an irrational number.

Therefore, 9 is an irrational;

3 is an irrational number

(iii) We have, = = 1.2

Every terminating decimal is a rational number, so 1.2 is a rational number.

(iv) we have, = = = Quotient of a rational and an irrational number is irrational number. Therefore, it is an irrational number.

(v) - = - = - 8 = -8/1

AS it can be expressed in the form of , so it is a rational number.

(vi) = 10 = Thus it can be expressed in the form of , so it is a rational number.
