Classify the following numbers as rational or irrational:

(i) √23 = 4.79583152331… Since, the number is non-terminating and non-recurring hence, it is an irrational number

(ii) √225 = 15 = 15/1 It is a rational number as it can represented in the form of p/q

(iii) 0.3796 Since, the number is terminating number. Therefore, it is a rational number

(iv) 7.478478 = 7.4͞7͞8 Since, the number is non-terminating recurring number. Therefore, it is a rational number

(v) 1.101001000100001… Since, the number is non-terminating non-repeating. Hence, it is an irrational number
