A fraction is an expression representing a quotient of one number (or expression) by another number (or expression).

It is usually expressed in the form:

$\dfrac a b$


$a / b$

where $a$ and $b$ are either numbers or expressions.

The term fraction is usually encountered when $a$ and $b$ are integers.

In this case, the fraction $\dfrac a b$ represents a rational number.
