If we consider the set of rational numbers and the set of irrational numbers, what elements are present in both sets?
Show answer & explanation
Correct answer: D
Explanation
Rational numbers are those that can be written in the form p/q, where q ≠ 0.
Irrational numbers are those that cannot be written in the form p/q.
Therefore, a number cannot be both rational and irrational.
There are no common elements between the two sets (empty set, ∅).
