The number 15 belongs to an infinite amount of sets.
30 belongs to the set of natural numbers
10 belongs to the set "natural numbers", but it can also belong to whole numbers, and rational numbers
integers
It belongs to any set that has -17 amongst its members.Given that this is schoolwork, the answer teacher probably wants is: the set of integers.It also belongs to the set of rational numbers, the set of negative integers, the set of real numbers, the set of complex numbers, the set {43.2, 98, -17, pi} and an infinite number of others.It belongs to the set of complex numbers in spite of having no 'imaginary' part. Real numbers are just special cases of complex number in which the imaginary part happens to be zero. Rational numbers are special cases of real numbers. Integers are special cases of rational numbers.

The number 15 belongs to an infinite amount of sets.
Rational numbers and Real numbers
30 belongs to the set of natural numbers
Real numbers; also the rational numbers.
10 belongs to the set "natural numbers", but it can also belong to whole numbers, and rational numbers
Any number that can be written as a fraction belongs to the set of rational numbers.
Because that is how the set of integers and the set of rational numbers are defined.
