Frequently asked questions

Can I convert a repeating decimal?

The tool is designed for terminating decimals such as 0.75. A repeating decimal usually requires a different algebraic approach, so the result may not be suitable unless you first express the value in an accepted form.

Is the fraction simplified automatically?

The displayed fraction matches the decimal you provide and may be simplified. To confirm, divide the numerator by the denominator and compare the result with the original decimal value.

What should I enter if my decimal uses a comma?

Use a dot instead if the tool expects that separator, as in 0.75. A comma can be read differently depending on regional settings, so check the output after conversion to make sure the value is correct.
