Question

Which of the following statements is false?
A.Whole numbers are never irrational.
B.There are no integers that are whole numbers.
C.There is only one whole number that is not a natural number.
D.Natural numbers cannot be negative.

Answer 1

B

Answer 2

B.

A is true as whole numbers indeed are always rational -- e.g.
0/1,1/1,2/1,...

B is true as the set of non-negative integers is actually identical to the whole numbers.
C is true depending on the convention chosen for what defines a natural number. For natural numbers defined as follows...
1,2,3,...

i.e. not including zero, then indeed it's difference from the set of whole numbers is
{0}

D is true because regardless of convention it is agreed upon that natural numbers are at least non-negative.
