Frequently asked questions
How do you convert a decimal to a fraction?
Use the decimal's place value as the denominator (e.g. 0.75 has 2 decimal places, so it's 75/100), then simplify to lowest terms.
What about repeating decimals like 0.333...?
Since you can only type a finite number of digits, the calculator converts exactly what you entered (e.g. "0.333" becomes 333/1000) rather than detecting a repeating pattern.
Does this work for negative decimals?
Yes — the sign carries onto the numerator in the result.
