How do I enter a mixed number?

Enter the whole part in the "Whole" field and the fractional part in the Numerator and Denominator fields. For example, 2 1/3 would be Whole=2, Numerator=1, Denominator=3. For a simple fraction like 3/4, leave the Whole field blank or set it to 0.

How are fractions simplified?

The calculator divides both the numerator and denominator by their Greatest Common Divisor (GCD) to produce the fully reduced fraction. The sign is always kept on the numerator; the denominator is always positive.

What happens when I divide by zero?

If the denominator of either fraction is zero, or if you attempt to divide by a fraction with a numerator of zero, the calculator shows a friendly error message instead of computing a result.

Can I enter negative fractions?

Yes. Enter a negative whole number (e.g. -2) to make a mixed number negative. For a simple negative fraction with no whole part, enter a negative numerator (e.g. Whole blank, Numerator=-3, Denominator=4).

How accurate is the decimal result?

The decimal is calculated using JavaScript floating-point arithmetic and displayed to up to 8 decimal places with trailing zeros removed. For repeating decimals this is an approximation.
