Let's go through this term by term.
- Rational number- a number that can be expressed as a fraction.
Since -6 is obviously not a fraction, it is not a rational number.
- Irrational number- a number that cannot be expressed as a fraction- has an infinite amount of numbers when written as a decimal.
Again, -6 isn't infinite nor is it a decimal or fraction- that's out of the way.
- Whole number- a number; an integer.
An integer (or whole number) includes positive and negative numbers- so -6 is a whole number and an integer! You can put either though, since they are both the same.
- Real numbers- numbers that are either algebraic or transcendental, rational or irrational, or positive, negative, or 0.
Since -6 is a negative number, it is a real number as well.
Answer: Whole number, integer, and real number
