- 1Type the first fraction: a plain fraction (3/4), a mixed number (1 1/2), a whole number, or a decimal (0.75).
- 2Choose the operation, then type the second fraction.
- 3Press Calculate and read the result with its step-by-step working.
1/3 + 1/6: the common denominator is 6, so 1/3 becomes 2/6, then 2/6 + 1/6 = 3/6, which simplifies to 1/2. The result panel shows fraction 1/2, mixed number 1/2, decimal 0.5 and 50%.
- All arithmetic is exact integer arithmetic on numerators and denominators; nothing is rounded until the decimal and percent displays, which are labeled with their rounding (6 and 2 decimal places).
- Decimals you type are converted exactly from their digits, so 0.1 is treated as 1/10, not as the binary approximation your calculator might use.
- Very large numerators and denominators (beyond about 15 digits) can exceed the exact whole-number range of the browser and are not supported.
- Mixed numbers use a space: write 1 1/2 for one and a half. A negative mixed number is written -1 1/2.
The tool is built for learning and checking homework. The steps show the common denominator, the numerator arithmetic and the simplification, so you can compare with your own working line by line.
About this tool
The Fraction Calculator adds, subtracts, multiplies, divides and compares fractions using exact whole-number arithmetic, so 1/3 + 1/6 comes out as exactly 1/2 rather than a rounded decimal. Every answer comes with the worked steps, the simplified fraction, the mixed number, and decimal and percent forms.
