Answer 1

Explanation Below

Explanation:

Rational numbers come in 3 different forms; integers, fractions and terminating or recurring decimals such as `1/3`.

Irrational numbers are quite 'messy'. They can't be written as fractions, they are never-ending, non-repeating decimals. An example of this is the value of `π`.

A whole number can be called an integer and is either a positive or negative number, or zero. An example of this is `0`, `1` and `-365`.
