Counting numbers are a proper subset of whole numbers which are the same as integers which are a proper subset of rational numbers.
I would hope all elections use rational numbers: all Counting numbers are Rational numbers.
-3 is a real, rational, whole integer. But then, -- All integers are real rational whole numbers. -- All whole numbers are real rational integers. -- All rational numbers are real. -- All counting numbers are real, rational, whole integers.

They are not. They are countably infinite. That is, there is a one-to-one mapping between the set of rational numbers and the set of counting numbers.
Yes, they are.

First of all counting numbers (positive integers) are rational numbers so without rational numbers there would be no counting. You could not equitably share one item between two or more people without fractions (rational numbers). Everything does not come in whole numbers - there are times when you need half-a-day, or 2.5 teaspoons, etc.

Every counting number, and the negative of it, are real, rational integers.
Natural numbers or Counting numbers Integers Rational numbers Irrational numbers
Every whole number is rational and an integer. But the "natural" numbers are definedas the counting numbers, so the negative whole numbers wouldn't qualify.No and yes: it is not a natural number but it is a rational number.
No, it is a rational number. Numbers in the form of a/b, where a and b are integers, are called rational numbers. 0.666... can be written as 20/3. So it is a rational number.
