I.irrational

j.√121=11;rational

k.rational

Answer 2

Answer:

Rational:- a) 1.3 = 13/10      b) -2.35 = -235/100    c) 0.6 = 6/10   d)0.1111 = 1/9

f) √25 = 5 = 5/1    g) 0.625 = 625/1000  j) √121 = 11 =11/1   k) 0.7373 = 73/99

Irrational :-   d) √7 = 2.64...... = not ending and all values are different so cant express in fraction

Similarly  h)√8 3 , i) √3

hope you got it
