Embed the Fraction Calculator
Add, subtract, multiply or divide fractions and mixed numbers, with an exact reduced answer and every step shown. Set the values it should open on, then copy the iframe. Your visitors can change them; the widget recomputes against Rule Calculator and never touches your page.
Opening values
Set what the widget shows before anyone touches it. Leave a field as it is and it stays out of the URL.

The one condition is the credit link inside the widget, which is how the calculator stays free. Want the numbers in your own markup instead?
