5 belongs in the sets:
-Natural number set, positive whole numbers
-Integer number set, whole numbers
-Rational number set, numbers that are not never ending
-Real number set, basic numbers without i and that can be expressed in say amounts of apples
-Complex number set, the set that contains both real and unreal numbers
Irrational numbers.
The Rationals, the set {1, 3 , 5.86, sqrt(59), -2/3, pi2}, the reals numbers, numbers between 5 and 6, etc.
mixed numbers
composite
Rational positive numbers
-5
The set of numbers which 3 does not belong is the set of even numbers.
Integers. (This includes negative whole numbers.)
10 belongs to the set "natural numbers", but it can also belong to whole numbers, and rational numbers
A set is just a way of describing numbers, and numbers can be described in more than one way. If set A is (for example) all positive prime numbers, and set B is all numbers between 0 and 10, then there are some numbers (2, 3, 5, and 7) that could belong to both sets.
The integers. Also: the rational numbers, the real numbers and (depending on your definition) the complex numbers.
Counting numbers
Irrational numbers.
The Rationals, the set {1, 3 , 5.86, sqrt(59), -2/3, pi2}, the reals numbers, numbers between 5 and 6, etc.

It belongs to the set of prime numbers
