Fraction Calculator
The Fraction Calculator adds, subtracts, multiplies, and divides two fractions — including mixed numbers with a whole part — and shows the answer reduced to lowest terms as a fraction, a mixed number, and a decimal.
Result
5/6
Enter an optional whole number plus a numerator over a denominator for each fraction. Results are automatically reduced to lowest terms and shown as a mixed number, an improper fraction, and a decimal.
How This Tool Works
Enter each fraction as an optional whole number plus a numerator over a denominator, pick an operation, and the simplified answer appears instantly as a mixed number, an improper fraction, and a decimal.
Formula & Method
Each entry is converted to an improper fraction. Addition and subtraction use a common denominator (a/b ± c/d = (ad ± bc)/bd); multiplication multiplies across (ac/bd); division multiplies by the reciprocal (ad/bc). The result is reduced by its greatest common divisor.
Example Calculation
One half plus one third: 1/2 + 1/3 = 3/6 + 2/6 = 5/6, which is already in lowest terms and equals about 0.8333 as a decimal.
Frequently Asked Questions
Can it handle mixed numbers?+
Yes. Enter a whole number alongside the numerator and denominator (for example 2 and 1/4 for two and one-quarter) and the calculator converts it automatically.
Does it simplify the answer?+
Always. The result is automatically reduced to lowest terms using the greatest common divisor, and also shown as a mixed number and a decimal.
Can I use negative fractions?+
Yes — put a minus sign on the whole number or numerator and the calculator tracks the sign through the operation.
