Name all sets to which -15 belongs to
all of your sets except natural and whole
To determine the sets to which -15 belongs, we need to consider different types of sets. Here are some possibilities:
1. The set of whole numbers (W): -15 is not a whole number since it is a negative number.
2. The set of integers (Z): -15 is an integer, so it belongs to this set.
3. The set of rational numbers (Q): -15 is a rational number since it can be expressed as -15/1. Therefore, it belongs to this set.
4. The set of real numbers (R): -15 is a real number, so it belongs to this set.
5. The set of irrational numbers (Irr): -15 is a rational number, so it does not belong to this set.
6. The set of natural numbers (N): -15 is not a natural number since it is a negative number.
Therefore, -15 belongs to the sets Z, Q, and R.
To determine the sets to which a number, in this case -15, belongs, we can consider various mathematical sets. Here are some notable sets in which -15 belongs:
1. Integer Set (Z): The set of all integers, including positive, negative, and zero. -15 is an integer, so it belongs to this set.
2. Rational Numbers (Q): The set of all numbers that can be expressed as a ratio of two integers. Since -15 can be written as -15/1, it is a rational number and belongs to this set.
3. Real Numbers (R): The set of all numbers that can be represented on a number line, including fractions, decimals, and irrational numbers. As -15 can be located on the number line, it is a real number.
4. Negative Numbers: The set of all numbers less than zero. Since -15 is a negative number, it is a member of this set.
Please note that there are several other sets in which -15 belongs, such as the subset of even numbers, subset of odd numbers, subset of whole numbers, etc. The sets listed above are just a few examples.
