The term "fifth" refers to the ordinal number that indicates the position of something in a sequence, specifically the one that comes after the fourth and before the sixth. It is commonly used in various contexts, such as ranking, measurements, and divisions. For example, in a race, the runner who finishes in fifth place is the fifth person to cross the finish line. In music, "fifth" can also refer to an interval between two notes. A perfect fifth is a specific distance between notes that is often found in scales and chords. In the context of fractions, one-fifth represents one part of a whole that is divided into five equal parts, often written as 1/5.
