Partitioning is dividing a set of things into subsets such that the union of all the subsets is the original set and the intersection of any two subsets is the null set. That is, between them, the subsets account for the whole of the original set and there are no elements in more than one subset.

An element doesn't have subsets. Sets can have subsets.

Two. The set {x} has the subsets {} and {x}.

A finite set with N distinct elements has 2N subsets.

A fraction is a number, it is not a set. A number cannot have subsets, only a set can.

The number of elements. A set with n elements has 2n subsets; for example, a set with 5 elements has 25 = 32 subsets.

Elements belong to subsets: subsets contain elements (from the parent set).

If the set has n elements, the number of subsets (the power set) has 2n members.

If the universal set contains N elements then it has 2N subsets.

That means, figure out how many different subsets a set has. In general, if a set has n elements, it has 2n different subsets.

They are collections of some, or all, of the elements of the set. A set with n elements will have 2^n subsets.
