To calculate a fraction, you need to understand how fractions work in addition, subtraction, multiplication, and division. When performing operations, always check if the fractions need a common denominator (for addition and subtraction) or if they can be multiplied or divided directly. You can also simplify the results to their lowest terms. Use our Fraction Calculator to get instant answers with step-by-step explanations.

To simplify a fraction, divide both the numerator and denominator by their greatest common divisor (GCD). For example, if a fraction is 8/12, divide both by 4 to get the simplified form 2/3. Simplifying helps in easier calculations and better readability.

To add fractions, the denominators must be the same. If they are different, find the least common denominator (LCD) and adjust the fractions accordingly. Then, add the numerators while keeping the denominator the same. Finally, simplify if necessary.
Example:
1/4 + 1/6 → Convert to a common denominator (12) → 3/12 + 2/12 = 5/12.

Subtracting fractions follows the same rule as addition. Convert fractions to a common denominator, then subtract the numerators while keeping the denominator unchanged. Finally, simplify if possible.
Example:
3/5 – 1/4 → Convert to a common denominator (20) → 12/20 – 5/20 = 7/20.

Multiplication of fractions is straightforward—multiply the numerators and multiply the denominators. Simplify the result if needed.
Example:
2/3 × 4/5 = (2×4) / (3×5) = 8/15.

To divide fractions, flip the second fraction (take its reciprocal) and then multiply.
Example:
(2/3) ÷ (4/5) → (2/3) × (5/4) = (2×5) / (3×4) = 10/12 = 5/6.
