The term "fifth" refers to the position in a sequence that comes after the fourth. For example, in a race, the runner who finishes after the fourth place is said to be in fifth place. In music, a fifth can also refer to an interval between two notes, specifically the distance between the first and fifth notes of a scale, like in the C major scale.
In fractions, "fifth" represents one part of five equal sections, written as 1/5. This concept is often used in cooking, where a recipe might call for a fifth of a cup of an ingredient. Understanding "fifth" helps in both everyday situations and academic subjects like math and music.
