Whole numbers are non-negative integers. Part (i) is incorrect.

Following your definition of prime numbers: "... itself is not 1." Part (iii) is incorrect also.

Your definition for rational numbers is not quite complete as well. a and b are not restricted to just whole numbers, but all integers. And b must be non-zero.
