Answer 1

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
