Fraction Calculator

To add fractions with different denominators, first find the least common denominator (LCD). Convert each fraction to an equivalent fraction with the LCD, then add the numerators. For example: 1/3 + 1/4 = 4/12 + 3/12 = 7/12.

A proper fraction has a numerator smaller than its denominator (like 3/4). An improper fraction has a numerator equal to or larger than its denominator (like 5/4 or 4/4). Improper fractions can be converted to mixed numbers.

To simplify a fraction, divide both the numerator and denominator by their greatest common divisor (GCD). For example, to simplify 12/18, divide both by 6 to get 2/3. Our calculator automatically simplifies all results.

Yes! You can enter negative fractions by putting a minus sign before the numerator. For example, -3/4 or 3/-4. The calculator handles negative fractions in all operations correctly.

Multiply the whole number by the denominator, add the numerator, then place over the original denominator. For example: 2 1/3 = (2×3+1)/3 = 7/3.

Dividing by a fraction is the same as multiplying by its reciprocal. To divide by a fraction, flip it and multiply. For example: 1/2 ÷ 3/4 = 1/2 × 4/3 = 4/6 = 2/3.

Our calculator shows decimal equivalents up to 10 decimal places. For repeating decimals, we show the pattern and indicate it with notation like 0.333... or 0.1̄6̄.

Currently, the calculator works with two fractions at a time. For multiple fractions, calculate step by step - first calculate two fractions, then use that result with the next fraction.
