Fraction Calculator

This calculator performs addition, subtraction, multiplication, and division on two fractions, then automatically reduces the result to its simplest form.

For addition and subtraction, it cross-multiplies to find a common denominator. For multiplication, it multiplies numerators and denominators directly. For division, it multiplies by the reciprocal of the second fraction. The result is then simplified by dividing both numerator and denominator by their greatest common divisor.

Example: Adding 1/2 + 1/3 cross-multiplies to (1×3 + 1×2) / (2×3) = 5/6, which is already in its simplest form, equal to roughly 0.833333 as a decimal.
