How it works
Enter each fraction as an optional whole number plus a numerator and denominator (for example 1 and 3/4). The result is reduced to lowest terms and shown as a fraction, a mixed number, a decimal and a percentage.
- a/b + c/d = (ad + cb) / bd
- a/b × c/d = ac / bd
- a/b ÷ c/d = ad / bc
- simplify: ÷ gcd(n, d)
