Add, subtract, multiply and divide fractions and mixed numbers. Answers are simplified and shown as a fraction, mixed number and decimal. Nothing leaves your browser.
Type fractions as 3/4 or mixed numbers as 1 1/2 (whole numbers and negatives work too). The calculator uses exact integer arithmetic, then divides the top and bottom by their greatest common divisor to simplify.
Find a common denominator, add the numerators, then simplify. For example 1/2 + 1/3 = 3/6 + 2/6 = 5/6.
To multiply, multiply the numerators and the denominators. To divide, multiply by the reciprocal of the second fraction: 1/2 ÷ 1/4 = 1/2 × 4/1 = 2.
Type the whole part, a space, then the fraction, for example 1 1/2. Negative numbers start with a minus sign.
