The set {15}.
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.
Real numbers form a proper subset of the set of complex numbers.
A whole number is not a set of any kind and so cannot be a subset of rational numbers.
The subset consisting of the one number, 7.5 : {7.5}
The set of all rational numbers.If the set contains all of them then no other set can contain any more rational numbers.

Integers is a pretty general - that is, least specfic - set. I would say the solution set to the equation x + 2 = 0
Real numbers form a proper subset of the set of complex numbers.
A set which contains any irrational or complex numbers.
No, rational numbers are not a subset of integers.
Any set that contains it, for example, the set {1, 4/7, sqrt(5), -99} sqrt(5) is an irrational number which form a subset of real numbers which form a subset of complex numbers which ...
A whole number is not a set of any kind and so cannot be a subset of rational numbers.
It belongs to any set that contains it: for example, {4.75, -12, pi, sqrt(5), 29}. It belongs to the set of integers which is a proper subset of rational numbers which is a proper subset of real numbers which is a proper subset of complex numbers. So -12 belongs to all the above sets.

Integers
No. There are several real numbers that are not rational (e.g. pi). However, every rational number is also a real number. In general, whole numbers/natural numbers is a subset of the integers (i.e. every whole number is an integer), the integers is a subset of the rationals, the rationals are a subset of the real numbers. I think the real numbers are a subset of the complex numbers, but I'm not 100% positive on that.
