Use the place value of the numbers.
0.3333 = 3,333/10,000
Perhaps you are interested in the infinitely repeating decimal fraction
0.3333... (repeating infinitely)
The trick to converting any repeating decimal to a fraction is to put the repeating part over an equal number of 9s. Here, we have one repeating digit (3), so the fraction is 3/9 = 1/3.
