    Answer:Natural numbers are all numbers 1, 2, 3, 4… They are the numbers you usually count and they will continue on into infinity.

    Whole numbers are all natural numbers including 0 e.g. 0, 1, 2, 3, 4…

    Integers include all whole numbers and their negative counterpart e.g. …-4, -3, -2, -1, 0,1, 2, 3, 4,…

    All integers belong to the rational numbers. A rational number is a number


    Where a and b are both integers.

    Step-by-step explanation:

    The number 4 is an integer as well as a rational number. As it can be written without a decimal component it belongs to the integers. It is a rational number because it can be written as:




    or even




    is a rational number but not an integer.

    A rational number written in a decimal form can either be terminating as in:


    Or repeating as in


    All rational numbers belong to the real numbers.

    If you look at a numeral line


    You notice that all integers, as well as all rational numbers, are at a specific distance from 0. This distance between a number x and 0 is called a number’s absolute value. It is shown with the symbol


    If two numbers are at the same distance from 0 as in the case of 10 and -10 they are called opposites. Opposites have the same absolute value since they are both at the same distance from 0.
