Name the subset(s) of real numbers that -4 belongs to.
integers, rationals, reals

To determine the subset(s) of real numbers that -4 belongs to, we need to look at the different categories of real numbers.
1. Natural Numbers (N): These are the counting numbers starting from 1. -4 is not a natural number, so it does not belong to this subset.
2. Whole Numbers (W): Whole numbers are the set of natural numbers with the addition of zero. Since -4 is not a natural number but it is an integer, it belongs to the subset of whole numbers.
3. Integers (Z): Integers are all positive and negative whole numbers, including zero. -4 is an integer, so it belongs to the subset of integers.
4. Rational Numbers (Q): Rational numbers are numbers that can be expressed as the ratio of two integers, where the denominator is not zero. -4 can be written as -4/1, so it is a rational number.
5. Real Numbers (R): Real numbers include all rational and irrational numbers. Since -4 is not an irrational number (a number that cannot be expressed as a ratio of two integers), it belongs to the subset of real numbers.
Therefore, -4 belongs to the subsets of whole numbers, integers, rational numbers, and real numbers.
