What is a fraction?

Definition 1: A fraction represents a numerical value, which defines the parts of a whole. 

Definition 2: A fraction is a number that represents a part of a whole.

Generally, the fraction can be a portion of any quantity out of the whole thing and the whole can be any specific things or value.

The basics of fractions explain the top and bottom numbers of a fraction. The top number represents the number of selected or shaded parts of a whole whereas the bottom number represents the total number of parts.

Suppose a number has to be divided into four parts, then it is represented as x/4. So the fraction here, x/4, defines 1/4th of the number x. Hence, 1/4 is the fraction here.  It means one in four equal parts. It can be read as one-fourth or 1/4. This is known as fraction.
