What does the Fraction Calculator do?

It adds, subtracts, multiplies, or divides two fractions and returns the answer simplified to lowest terms, along with its decimal value and mixed-number form.

How does the fraction to decimal calculator part work?

After computing the simplified fraction, the tool divides the numerator by the denominator to show the decimal equivalent rounded to four decimal places.

How does the simplify fraction calculator reduce a result?

It finds the greatest common divisor (GCD) of the numerator and denominator with the Euclidean algorithm and divides both by it, producing the fraction in lowest terms.

Can the mixed number calculator handle negative fractions?

Yes. Negative numerators or denominators are normalized so the sign always sits on the numerator, and the mixed number keeps a single leading minus sign, like -1 1/2.

Does the multiplying fractions calculator cross-multiply for division?

For division, the tool multiplies the first fraction by the reciprocal of the second, which is the same as cross-multiplying, then simplifies the result.

Are the fractions I enter uploaded anywhere?

No. The Fraction Calculator runs entirely in your browser. The numbers you type are never sent to ArrayKit or anywhere else.

About Fraction Calculator

Fraction Calculator adds, subtracts, multiplies, and divides two fractions and reduces the answer to lowest terms automatically. Type a numerator and denominator for each fraction, choose an operation, and it finds a common denominator when needed, cross-multiplies for division, and simplifies with the greatest common divisor. The result appears as a reduced fraction, a decimal value, and a mixed number, so you can use whichever form fits your homework, recipe, or measurement. It is built for students checking arithmetic homework, teachers preparing examples, and anyone converting a fraction to a decimal or simplifying an ugly ratio. Everything runs locally in your browser — your numbers are never uploaded.

Common errors & troubleshooting

The Fraction Calculator shows an error about a denominator of zero. — A fraction with a denominator of 0 is undefined — double-check you did not swap the numerator and denominator fields.
Division gives an 'undefined' result. — Dividing by a fraction equal to zero (numerator 0) is undefined. Enter a non-zero numerator for the second fraction.
The result looks different from a textbook answer. — The Fraction Calculator always reduces to lowest terms, so 2/4 becomes 1/2. Multiply both parts by the same number if you need an equivalent, unreduced fraction.
A mixed number like '1 1/2' was typed into a single field and rejected. — Enter the whole number and fraction separately is not supported per field — use the numerator and denominator boxes for the fractional part only, or convert the mixed number to an improper fraction first (e.g. 1 1/2 = 3/2).
