What are the subsets for a fraction?

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


What determines the number of subsets in a set?

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


Why an empty set is a subset of every set?

An empty subset is a part of every set because it is necessary to satisfy the equation of subsets which is 2n. n= (number of elements). Therefore, an empty set is required to satisfy the formula of subsets.


What are the subsets of number 8?

The number 8 is not a set and so cannot have any subsets. The set consisting of the number 8 is a set and, since it has only one element in it, it has two subsets: itself and the null set.


How do you get the number of the subsets in a set?

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


Can you relate the number of elements of a set to its number of subsets?

If the set has "n" elements, then you can make 2n different subsets. The number of subsets will always be greater than the size of the set, both for finite and for infinite sets.


Can you form a formula that will tell how many subsets a set with union elements can have?

To find how many proper subsets there are in a set you can use the formula n^2 -n and if you would also like to find all subsets including improper the formula is n^2 -n +1


What is the number of subsets possible for the set in number 27?

A set with 27 members has 2^27 = 134217728 subsets - including itself and the null set.


How is it possible for a set to have an odd number of subsets?

It is impossible. If a set has n elements, the cardinality of its power set [the number of its subsets] is 2n which must be even.


How many subset has 01471112192124 have?

Only a set can have subsets, a number cannot have subsets.


Can we define the cardinal number as the number of subsets of that set?

No. The number of subsets of that set is strictly greater than the cardinality of that set, by Cantor's theorem. Moreover, it's consistent with ZFC that there are two sets which have different cardinality, yet have the same number of subsets.


What does find the number of subsets mean?

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