This decimal fraction converter rewrites the same value in another form: it converts a finite decimal to a fraction, or an integer fraction to a decimal. Decimal-to-fraction mode simplifies the result and shows a mixed number when the value has a whole-number part; fraction-to-decimal mode keeps the normalized fraction, its simplified form when needed, and the decimal value together.
If you need to add, subtract, multiply, divide, or compare two fractions, use the fraction calculator. If you only need the greatest common divisor of two integers, see the GCF calculator.
0.75 or 2.75 as a fraction.-6/8.The page has two directions: Decimal → Fraction and Fraction → Decimal. Choose the mode first, then fill in the fields for that direction so a fraction input is not accidentally used in decimal mode.
Decimal-to-fraction mode accepts ordinary decimal notation such as 0.75, -2.5, 3, .125, or 3.. A sign and a whole-number value are allowed, but scientific notation such as 1e-3 is not accepted, and the page does not infer the repeating part of a repeating decimal.
It supports finite decimal-to-fraction conversion and integer fraction-to-decimal conversion.
No. Fraction mode expects integer numerators and denominators, and the denominator cannot be zero.
Yes. The page forms a fraction from the decimal places and then reduces it with the greatest common divisor.
No. Decimal mode expects ordinary decimal notation and is designed mainly for terminating decimals.
An improper fraction is also shown as a mixed number when that form is useful; both forms represent the same value.
Convert finite decimals to fractions and integer fractions to decimals, with automatic simplification and mixed-number output when applicable.
