How this tool works
Addition and subtraction use a common denominator. Multiplication multiplies numerators and denominators directly. Division multiplies by the reciprocal of the second fraction.
Example
1/3 + 1/6 = 3/6, which reduces to 1/2 and equals 0.5.
Common questions
Can the result be negative?
Yes. Negative numerators or operations that produce a negative value are supported.
What happens if a denominator is zero?
The fraction is undefined, so the calculator will not produce a valid result.
