Is this number a rational number, irrational number, whole number, real number or integer

Let's go through this term by term.

Since -6 is obviously not a fraction, it is not a rational number.

Again, -6 isn't infinite nor is it a decimal or fraction- that's out of the way.

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.

Since -6 is a negative number, it is a real number as well.
