Open calculatorTo add or subtract fractions, you find the common denominator (LCM), convert each fraction to equivalent fractions with that common denominator, and combine the numerators.
A mixed number consists of an integer and a proper fraction. For example, 23/20 equals 1 whole with a remainder of 3/20 (1 3/20).
No. Division by zero is mathematically undefined. Denominators must always be non-zero integers.
Fractions represent parts of a whole or ratios between integers. Simplifying fractions requires dividing both the numerator and denominator by their greatest common divisor (GCD).
