Numbers that are non-negative integers, such as 1,2,12,201,...

There are two definitions of natural numbers, one that includes 0, and the other one does not. Most high-school definitions include 0.

b.whole numbers

Whole numbers do not have decimals nor fractions. They can be positive, negative, or zero. Examples are -100, -23, 0, 40, 47,1729,...

c.integers

Integers are whole numbers. This term is a more technical term than "whole numbers".

d.rational numbers,

Rational numbers are whole numbers or fractions that can be represented by division of two integers, m/n. Whole numbers can be represented by an integer divided by 1.

Examples: 0, 3, 4/5, 144/17, 355/113, -45/13..., 0.4, 3.̅3 (=10/3),

e.irrational numbers

Irrational numbers are real numbers that are not rational, i.e. real numbers that cannot be represented as a quotient of two integers. Examples are: √2, -√94, π and e.

This should give you a good idea of how to classify numbers. Proceed with the exercise and post your answers for checking if you wish.

Note:

If you are wondering what a real number is:

a real number is a number that is not complex. A complex number includes an imaginary component, i. A real number is a subset of complex numbers, which has the general form**a+bi**, where a and b are real numbers, and i is the square-root of -1. When b=0, the number becomes a real number.
