Work Step by Step

$\bf{\text{Solution Outline:}}$ Use the definitions of the different classification of numbers. $\bf{\text{Solution Details:}}$ Natural numbers are the numbers $\{1,2,3,...\}$. Whole numbers are the numbers $\{0,1,2,3,...\}$. Integers are the numbers $\{...,-3,-2,-1, 0,1,2,3,...\}.$ Rational numbers are numbers that can be expressed as the ratio between $2$ integers. Irrational numbers are numbers that CANNOT be expressed as the ratio between $2$ integers. Real numbers are the combined numbers in the set of rational and irrational numbers. The given number, $ 0 ,$ is classified as \begin{array}{l}\require{cancel} \text{1) whole number, } \text{2) integer, } \text{3) rational number, } \text{4) real number} .\end{array}
