About Fraction Calculator
Adding and subtracting fractions needs a common denominator: multiply each fraction so both share one, combine the numerators, then reduce by the greatest common divisor. Multiplying is simpler — numerators together, denominators together — and dividing is multiplying by the reciprocal of the second fraction.
Mixed numbers are converted to improper fractions first, so three and a half becomes seven halves before anything else happens. The result is reduced automatically, which is why five tenths comes back as one half.
Frequently asked questions
- Can I use mixed numbers?
- Yes, enter the whole number alongside the fraction and it is converted automatically.
- Why is my answer different from what I expected?
- Results are always fully reduced, so 6/8 is shown as 3/4.
- What about dividing by zero?
- A zero denominator or dividing by zero is flagged rather than producing a nonsense answer.
