Answer: See below.

Step-by-step explanation:

Let's go number by number.

Rational pretty much means you can put it into a fraction of whole numbers.

The first number is -81,572.

This number is rational because it can be put into a fraction ( $\frac{-81572}{1}$ ) that is made up of whole numbers.

The second number is $\sqrt{11}$ .

This number is irrational because it cannot be put into a fraction of whole numbers.
Keep in mind that most squareroots are irrational. Especially those that don't equal a whole number.

The third number is 5.636336333
