Answer:
The set of rationals that are not integers
Explanation:
From the statement we have the set U and the set S which are the following:
U {the universal set = the set of all rational numbers}
S {set of all integers}
We are asked to calculate Sc, that is, the complement of the set S.
If U is all the numbers and S the integers, the complement of S are all the numbers that are not integers. That is to say:
Sc = U - S = rational numbers - set of integers
Therefore Sc would be more precisely the set of rationals that are not integers.
