Fraction Bar

Fraction Bar

Symbol used to separate the numerator from the denominator in a fraction or a rational expression.

The fraction bar is a vinculum, or a link between two objects considered as a whole.


The fraction bar symbol is a horizontal line as in \(\frac{2}{3}\) or \(\frac{2x\space+\space5}{3\space+\space5x}\).

In some texts or computer formulas in particular, an oblique line is used instead of a fraction bar: 2/3.
