How to use the fraction calculator
This fraction calculator adds, subtracts, multiplies, and divides two fractions and shows the result in simplified form. Enter the numerator and denominator of the first fraction, choose an operation (+, −, ×, or ÷), then enter the second fraction. Click "Get result" to see the answer as a fraction in lowest terms and, when the value is not a whole number, as a decimal. The calculator uses the greatest common divisor to reduce the result automatically, so you get a clean answer without doing common denominators or simplification by hand.
For addition and subtraction, the tool finds a common denominator, performs the operation, and simplifies. For example, 1/2 + 1/3 becomes 3/6 + 2/6 = 5/6. For multiplication, it multiplies numerators and denominators then simplifies (e.g. 2/3 × 4/5 = 8/15). For division, it multiplies by the reciprocal of the second fraction (e.g. 1/2 ÷ 3/4 = 1/2 × 4/3 = 2/3). Denominators must be non-zero; for division, the second fraction's numerator must not be zero. Negative fractions are supported.
Use this calculator for homework, recipes, measurements, or any situation where you need to combine or compare fractions. The layout is responsive: the input grid (Fraction 1 | Operation | Fraction 2) stacks on small screens so you can use it on phones and tablets. Results are always in lowest terms, and the optional decimal helps you interpret the value quickly. This page is optimized for search with clear, focused content so you can find and use the fraction calculator whenever you need it.
