In mathematics, a colon (:) is often used to denote a ratio or a division between two quantities. For example, the expression "a : b" represents the ratio of (a) to (b). Additionally, in set notation, a colon can indicate such a relationship as in "x ∈ A : P(x)", meaning "x is an element of set A such that property P holds for x."
