Step-by-step explanation:
A rational number can be expressed in the form
[tex]\frac{a}{b}[/tex] ← where a and b are integers
An example is
[tex]\frac{2}{3}[/tex]
- 5 can be expressed as [tex]\frac{-5}{1}[/tex] and is therefore rational
Numbers which are not rational are irrational
π and [tex]\sqrt{2}[/tex] are examples of irrational numbers
