Describe all the sets and subsets 2/3 belongs to

Answer 1

The set containing 2/3 is the set {2/3}.

As for its subsets:
- The empty set {} is a subset of every set, including the set {2/3}.
- The set {2/3} itself is a subset of itself.
- Additionally, the power set of {2/3}, denoted by P({2/3}), is the set containing all possible subsets of {2/3}, which consists of two subsets: the empty set {} and the set {2/3}.
