Step-by-step explanation:

• in (i) ,  the reciprocal of rational is always an rational .
• in (ii) , if the two irrational number is positive and negative with same magnitude then their sum is zero which is an rational.

                         e.g . √5 + ( -√5 ) = 0

• in (iii) , it is true.

                        e.g. between 5 and 6

                                       5.56556555655556------ and 5.667666766667-----

• in (iv) , it is true . we all know that very well

                        e.g. let x and (x+1) are p and q , then

                (p + q)/2 = [x + (x+1)] / 2 = x + 1/2 which is a rational number .
