real rational and whole
because an irrational number is an infinite number for example 13.125817357183 ... / a whole number are all the positive numbers you know / a rational number is any number that can be represented as the quotient of two whole numbers or, more precisely, an integer and a positive natural; 1 that is, a common fraction a / b with numerator a and denominator b other than zero, therefore 36 is an integer and the whole numbers are part of the rational numbers.
