Answer:
Only a Rational Number
Step-by-step explanation:
An integer must be a whole number that can be positive negative or zero
8.1 isn't a whole number because it is a decimal
A rational number is a number that can be written as a fraction like 1/10. π is an example of an irrational number and cannot be written as a fraction.
81/10 = 8.1 therefore it is a rational number
