To any set that contains it!
It belongs to {18},
or {sqrt(2), 18, pi, -3/7},
or {18, bananas, France, cold}
or all whole numbers between 3 and 53,

or composite numbers,
or counting numbers,
or integers,
or rational numbers,
or real numbers,
or complex numbers,
etc.
Rational (ℚ) which is a subset of Real (ℝ) which is a subset of Complex (ℂ).

I'm just telling you this ahead of time...but i'm not 100% sure with this answer..: fractions belong in the Rational Numbers
-4.2 is a negative decimal number. It is also a directed number.
-28 belongs to: Integers, which is a subset of rationals, which is a subset of reals, which is a subset of complex numbers.
No, they can belong to infinitely many subsets.
Rational (ℚ) which is a subset of Real (ℝ) which is a subset of Complex (ℂ).
A subset, A, of a given a set S, consists of none or more elements that belong to S.
Negative numbers.
They are irrational numbers
Irrational Numbers which are a subset of Real Numbers which are a subset of Complex Numbers ...
Because all its elements belong to itself.
It belongs to the rational numbers which is a subset of the real numbers. The reals, in turn, is a subset of complex numbers.

It belongs to any subset which contains it. For example,the interval (3, 4){pi}{1, pi, 3/7}{27, sqrt(7), pi}
