Asked 11 years, 3 months ago. The set of rational numbers q ˆr is neither open nor closed. By between two real numbers exists. It isn’t open because every. a set is unbounded if and only if it is not bounded. the sets [a, b], ( − ∞, a], and [a, ∞) are closed. Therefore, ℚ = 𝑎 𝑏 ∶ 𝑎,. Recall that if s ⊂rn s ⊂ r n, then the complement of s s, denoted sc s c, is. Indeed, ( − ∞, a]c = (a, ∞) and [a, ∞)c = ( − ∞, a) which are open by. We begin by recalling that the set of rational numbers, written ℚ, is the set of all quotients of integers.
