About the Fraction Calculator
This fraction calculator adds, subtracts, multiplies, and divides two fractions and returns the result as a simplified fraction along with its decimal equivalent. It handles negative fractions and automatically reduces the result to its lowest terms.
Useful for school homework, cooking and recipe scaling, woodworking measurements, and any situation where you need to work with fractions rather than decimals. Enter each fraction's numerator and denominator, choose an operation, and get the simplified answer instantly.
Frequently asked questions
Does it simplify the result?
Yes — every result is reduced to lowest terms by dividing numerator and denominator by their greatest common divisor. So 4/8 becomes 1/2 automatically.
Can I enter mixed numbers?
Yes — write '1 1/2' (with a space) for one and a half. Internally it converts to 3/2 for the calculation. Results are shown both as improper fractions and as mixed numbers when applicable.
