\(\sf \color{magenta}{Rational~Number}\)
A rational number is a number
that can be written as a ratio.
That means it can be written as a fraction
Such as 5 and 3.25 and -2

\(\sf \color{magenta}{Natural~Number}\)
Natural Numbers are all
the positive integers (whole numbers)
1, 2, 3, etc.

\(\sf \color{magenta}{Whole~Number}\)
Whole Numbers are all countable numbers
-2, -1, 0, 1, 2, 3, etc.

\(\sf \color{magenta}{Integers}\)
Integers are whole numbers, and never
fractions or decimals.
