To any set that contains it!
It belongs to {sqrt(5)},
or {45, sqrt(2), pi, -3/7, sqrt(5)},
or real numbers between -3 and 3
etc.
Real numbers form a proper subset of the set of complex numbers.
A subset is a smaller set that is part of a larger set. For example, the set of animals contains the subset of reptiles, the subset of mammals, and various others. Or in mathematics, the set of real numbers contains the subset of positive integers, the subset of negative integers, the subset of rational numbers, etc.
The set {15}.
You have it backwards. Integers are a subset of real numbers.
The real numbers, themselves. Every set is a subset of itself.

No because natural numbers are a subset of real numbers

Imaginary numbers are not a subset of the real numbers; imaginary means not real.
Starting at the top, we have the real numbers. The rational numbers is a subset of the reals. So are the irrational numbers. Now some rationals are integers so that is a subset of the rationals. Then a subset of the integers is the whole numbers. The natural numbers is a subset of those.
