To convert a decimal to a fraction, write the digits over 10, 100, 1000 and so on (one zero per decimal place), then simplify by dividing both numbers by their greatest common divisor. Pick a decimal below for the worked answer, or use the decimal to fraction converter. Decimals that repeat (0.333…, 0.1666…)? See the repeating decimal chart. Going the other way? See fraction to decimal.
