(i) False, here √2 is an irrational number and 3 is a rational number, we know that when we divide irrational number by non-zero rational number it will always give an irrational number.

(ii) False, because between two consecutive integers (likel and 2), there does not exist any other integer.

(iii) False, because between any two rational numbers there exist infinitely many rational numbers.

(iv) True, because there are infinitely many numbers which cannot be written in the form p/q, q ≠0. p,q both are integers and these numbers are called irrational numbers.
