This calculator shows the result of adding, subtracting, multiplying, or dividing two fractions as both a fully simplified fraction and a decimal at the same time. It's useful for checking elementary and middle school fraction problems or for cooking measurements and ratio calculations.
How to use
- Enter the numerator and denominator of the first fraction.
- Select the operator in the middle (+ − × ÷).
- Enter the numerator and denominator of the second fraction, and the simplified fraction and decimal result appear instantly.
- Use the copy button to copy the fraction or decimal result.
FAQ
- Does the result also come out as a mixed number?
- Yes. If the result is an improper fraction, a mixed number in the form 'whole remainder/denominator' is shown next to the simplified fraction.
- What happens if I put 0 in a denominator or divide by 0?
- If a denominator is 0, or the second numerator is 0 in a division, the calculation isn't valid, so it shows an explanatory note and doesn't compute a result.
- Is the value I enter sent to a server?
- No. All calculations are processed in your browser, and the fraction values you enter are never sent to or stored on a server.
