Frequently Asked Questions

Accuracy, everyday use, and how the step-by-step solvers are built.

Fraction conversions use exact integer division. A repeating decimal is written with the repeating digits in parentheses, so 5/6 is 0.8(3) and 83.(3)%, rather than a rounded approximation.

Choose a tool from the homepage, or open a conversion address such as /convert/3-4-as-a-decimal. Enter a fraction. The decimal, percent, and steps update on the page.

The solver reads the numerator and denominator, divides to find the decimal, multiplies by 100 for the percent, simplifies by the greatest common divisor, and lists equivalent fractions. Each of those moves is written out beside the answer.

Yes. The layout reflows for narrow screens, and the calculations run in the browser. You can search, convert, and read the steps without installing an app.

No. The tools are open in the browser. There is no sign-in, and a finished conversion page can be shared by its address.
