A fraction originally refers to a part of a whole, or more generally, any part of an equal number. It is expressed as a ratio of an integer a to an integer b (it is debatable whether a is a multiple of b is a fraction).
A fraction indicates that a number is a fraction of another number, or the ratio of one event to all events. The unit "1" is divided into several parts, and the number of such parts or parts is called a fraction. The numerator is on top and the denominator is on the bottom.
