Answer: Rational
Step-by-step explanation: Let's first go over what a rational number is. A rational number is any number that you can write in the form [tex]\frac{a}{b}[/tex] where a and b are integers and b ≠ 0.
The fraction [tex]\frac{2}{9}[/tex] would be a rational number because it's in the form of [tex]\frac{a}{b}[/tex]. Therefore, 2/9 is a rational number.
