The set of integers, rational numbers, real numbers, complex numbers are some of the sets. Also, many of their subsets: for example, all numbers divisible by 3.
The two main DISJOINT subsets of the Real numbers are the rational numbers and the irrational numbers.
It belongs to the interval (25, 27.3), or [-20.9, 10*pi], and infinitely more such intervals.It also belongs to the set of rational numbers, real numbers, complex numbers and quaternions.
There are infinitely many subsets of real numbers. For example, {2, sqrt(27), -9.37} is one subset.
Rational numbers.
Only a set can have subsets, a number such as -2.38 cannot have subsets.
