➗ Fraction Calculator
How It Works
Add, subtract, multiply, and divide fractions with automatic simplification. Use Fraction Calculator to apply the displayed mathematical method to your values and see the result immediately.
The result is most useful when the inputs match the definitions used by this calculator. For this tool, the underlying method is: Addition: a/b + c/d = (ad + bc)/bd. Simplify by dividing numerator and denominator by their GCD.. Compare the output with the worked example, then change one meaningful input at a time to see how the result responds.
Understanding Fraction
Fraction describes a mathematical relationship between the values entered in the calculator. Understanding the reference values and formula helps you interpret the result correctly.
Keep in mind: Check units, signs, reference values, and rounding conventions when using the result for an important calculation. Review the fraction inputs and units before relying on the result.
When to Use This Calculator
Use Fraction Calculator to apply the displayed mathematical method to your values and see the result immediately.
Practical tip: For this Fraction Calculator, identify the reference values and units first, then change one meaningful input at a time so the effect on the result is clear.
Formula
Addition: a/b + c/d = (ad + bc)/bd. Simplify by dividing numerator and denominator by their GCD.
Example
1/4 + 1/3 = (3 + 4)/12 = 7/12. 2/3 × 3/4 = 6/12 = 1/2.
