Fraction Calculator — Detailed Guide & Expert Explanation
You enter two fractions and select an operation. The calculator applies fraction rules, reduces results, and may show decimal equivalents. Some versions support mixed numbers or improper fractions.
By automating fraction math, the tool reduces errors and speeds up calculations.
Formula & Calculation Method
a/b + c/d = (ad + bc) / bd
a/b × c/d = (ac) / (bd)
The calculator uses standard fraction arithmetic. For addition and subtraction, it finds a common denominator. For multiplication and division, it multiplies numerators and denominators directly. Results are simplified using greatest common divisor (GCD) reduction.
