A rational expression is a fraction in which the numerator and/or denominator are polynomials (expressions of more than two algebraic terms). You can simplify a rational expression by reducing it to its lowest terms. To do this, divide out the common factors in the numerator and denominator.

Websites such as Mathportal.org offer calculators capable of simplifying rational expressions. Enter the expression into the website interface, and the calculator does the work for you. Since simplifying rational expressions mostly involves multiplying and dividing, you can also use a regular calculator to do most of the work.
