How fraction arithmetic works

This calculator handles all four arithmetic operations on fractions. For addition and subtraction it finds the LCD (Least Common Denominator), for multiplication it multiplies numerators and denominators directly, and for division it multiplies by the reciprocal. Results are always simplified using the GCD (Greatest Common Divisor), so 6/8 becomes 3/4 automatically.

To find the GCD or LCM of two numbers directly, use the GCD/LCM Calculator. For percentage problems, see the Percentage Calculator.
