Fraction, Common
A fraction is a mathematical expression that states the ratio between two numbers. The adjective common in the term common fraction means that both numbers involved are integers, or whole numbers. The common fraction ¾ can be thought of as the whole number 3 being compared to the whole number 4 in some way or another. A common fraction is generally written with the two numbers separated by a diagonal or horizontal line, as ¾. The number above the line is the numerator of the fraction, and the number below the line, the denominator of the fraction. The diagonal or horizontal line separating the numerator and denominator is mathematically equivalent to the division sign (÷) or the ratio sign (:).
