What is a fraction bar - Definition and examples
A fraction bar is a horizontal bar that separates the numerator and the denominator of a common fraction.
It is also common to use a forward slash ( / ) as a diagonal fraction bar. For example, if you write the fraction as 6 / 7, / could also be called a fraction bar.
The horizontal line or forward slash cannot be called fraction bars if the number on top and the number at the bottom of the fraction bar are not integers.
For example, in 2.5 / 6, / is not a fraction bar because 2.5 is not an integer.
