Classification of numbers according to the Venn diagram:
Rational numbers:
These numbers are represented by a fraction a / b, where a and b are integers and also b is different from zero.
Whole numbers:
An integer is a natural number that can be positive or negative.
Natural numbers:
Natural numbers are those that start at zero to infinity are clearly positive.
Rational numbers:
When taking the square root of 8, 36 and 4 the result is an exact value that is why they are considered as rational numbers.
Irrational Numbers:
When the root of a number is not exact but is expressed as an infinite decimal as in the case of the square root of 140 which is 11.83215956619; this is an irrational number, also this result cannot be expressed as a fraction.
