The universal set is the set of rational numbers. S is the set of integers.

Which represents Sc?

The set of rationals that are not integers

Step-by-step 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.
