Real, rational, non-integer, negative

Work Step by Step

There is a negative sign in front of the number, so we know that it is negative. Because it is a repeating decimal, we know that we can write this number as a fraction containing integers in the numerator and the denominator, so it is rational. Because all rational numbers are real numbers, we know that it is a real number as well. It is a decimal, so we also know that it is a non-integer.
