A proper subset of a set A is a subset of A that is not equal to A. In other words, if B is a proper subset of A, then all elements of B are in Abut A contains at least one element that is not in B.
For example, if A={1,3,5} then B={1,5} is a proper subset of A. The set C={1,3,5} is a subset of A, but it is not a proper subset of A since C=A. The set D={1,4} is not even a subset of A, since 4 is not an element of A.

What is the number of proper subsets of a given finite set with n element?
2n - 1
Does every set have a proper subset?
No. The null set cannot have a proper subset. For any other set, the null set will be a proper subset. There will also be other proper subsets.
How do you convert proper fractions into improper fractions?
You cannot. They are two disjoint subsets of rational numbers.
What is the number of proper subsets for 16187191?
If you start with a set with only one element [16187191] then there can be only one proper subset: the empty set.
What are proper subsets and improper subsets?
If set A is a subset of set B, that means that all elements in set A are also in set B. In the case of a proper subset, there is the additional specification that the two sets are not equal, i.e., there must be an element in set B that is not also an element of set A.
