No, by definition. A proper subset is a subset that contains some BUT NOT ALL elements of the original set.
give example of subset
no
{1,2,4.7} is a proper subset of {1, 2, 3, 4, 4.7, 5}
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.

NO- by definition a set is not a proper subset of itself . ( It is a subset, but not a proper one. )

Proper subset definitionA 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.
The set of Rational Numbers is a [proper] subset of Real Numbers.
Let A be the set {1,2,3,4} B is {1,2} and B is a proper subset of A C is {1} and C is also a proper subset of A. B and C are proper subsets of the set A because they are strictly contained in A. necessarily excludes at least one member of A. The set A is NOT a proper subset of itself.
Because every set is a subset of itself. A proper subset cannot, however, be a proper subset of itself.
the difference between a subset and a proper subset
Since ASCII ⊊ unicode, I don't know if there are ASCII codes for subset and proper subset. There are Unicode characters for subset and proper subset though: Subset: ⊂, ⊂, ⊂ Subset (or equal): ⊆, ⊆, ⊆ Proper subset: ⊊, ⊊,
