Enter the numerators and denominators of two fractions, choose an operation (add, subtract, multiply, divide), and click "Calculate". The result will be automatically simplified and shown as a decimal too.
No, division by zero is undefined. The calculator checks for zero denominators and will alert you if found.
Simplifying a fraction means dividing both numerator and denominator by their greatest common divisor (GCD) to get the smallest possible numbers. For example, 4/8 simplifies to 1/2.
