Solution:
(i) True, because natural numbers are part of whole
numbers.
(ii) False, because integers consist of negative
numbers as well as positive numbers while whole
numbers are 0 and positive integers.
As negative integers are not part of whole
numbers, the statement is false.
(iii) False, because rational numbers are of the
form where q is not equal to. So, every
whole number is a rational numbers but not
vice versa.
