Question 933195: List all subsets for the set {6,9}. Which of these subsets is not a proper subset?

You can put this solution on YOUR website!
all subsets for the set {6,9} are: S={ }, {6}, {9}, {6,9}
S is a proper subset of a set A if S is a subset of A but S%3C%3EA.
Therefore, the only set that is not a proper subset of A is the set A itself. In other words, only subset {6,9} is not a proper subset.
