FAQ

How do I convert a fraction to a decimal?
Divide the numerator by the denominator. For example, 3/4 = 3 divided by 4 = 0.75. Some fractions produce repeating decimals: 1/3 = 0.333... The tool handles both terminating and repeating decimals.
How do I convert a decimal to a fraction?
For terminating decimals: count decimal places, use as denominator power of 10, then simplify. 0.75 = 75/100 = 3/4. For repeating decimals, algebraic methods are needed. The tool does this automatically.
Which fractions produce repeating decimals?
A fraction produces a terminating decimal only if the denominator's prime factors are only 2 and/or 5. All other fractions repeat. Examples: 1/4 = 0.25 (terminates), 1/3 = 0.333... (repeats), 1/7 = 0.142857... (repeats).
