A fraction is a number, it is not a set. A number cannot have subsets, only a set can.
thenumber of subsets = 8formula: number of subsets =2n; wheren is thenumber of elements in the set= 2n= 23= 8The subsets of 1,2,3 are:{ }, {1}, {2}, {3}, {1,2}, {2,3}, {1,3}, {1,2,3}
The number of elements. A set with n elements has 2n subsets; for example, a set with 5 elements has 25 = 32 subsets.
There are 512 subsets in 123456789. This is because there are 9 elements. Take 2, and make it to the 9th power, this is 512, so there are 512 subsets.
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.
A set with 9 elements has 2^9 = 512 subsets.
meaning of proper subsets
The set of rational numbers. 23.8 can be expressed as the fraction 119/5
An element doesn't have subsets. Sets can have subsets.
There are no subsets of irrational numbers. There are subsets of rational numbers, however.
You cannot. Whole numbers and mixed numbers are two different subsets of the set of numbers.
Elements belong to subsets: subsets contain elements (from the parent set).
Elements can belong to subsets. Subsets can be elements of sets that are called "power sets".
32 different kinds of subsets

5 subsets of 4 and of 1, 10 subsets of 3 and of 2 adds up to 30.
