No, not all of them are rational numbers.

Rational numbers are numbers that can be expressed as a ratio of two integers.

In the given set, -2/4 and 0 are rational numbers because they can be expressed as -1/2 and 0/1, respectively.

However, 3.1 is not a rational number because it cannot be expressed as a fraction of two integers.

The square root of 81 (√81) is equal to 9, which is a rational number because it can be expressed as the fraction 9/1.
