    Hello from MrBill:

    Answers:

    a)  True.

          The set of natural numbers is the set of positive integers (1,2,3,4…) and

          sometimes  zero (0). 27 is a positive integer and thus a natural number.

    b)  True.     2.7 is not an integer  (it is a decimal value and a rational number)

    c) True.      Zero (0) is an integer, but not a positive or negative number.

    d) False.    -8 is an integer, a negative integer
