1.18 is a number and number do not contain any sets (of any kind).
It is an irrational number, and therefore a real number.
101, the only three-digit number. 10, the only even number. 11, the only number with all its digits the same.

There are an infinite number of sets of numbers. 9,10 an 11 9,9,10,11 and 11 9,9,9,10,11,11 and 11 etc, for example, is one family of sets of numbers.
10 because it's an even number !
The union of sets X and Y is the set consisting of all elements that belong to X, or belong to Y or to both.The union of sets X and Y is the set consisting of all elements that belong to X, or belong to Y or to both.The union of sets X and Y is the set consisting of all elements that belong to X, or belong to Y or to both.The union of sets X and Y is the set consisting of all elements that belong to X, or belong to Y or to both.
