Multiplying decimals by 100 will convert them to percentages.

If you wish to remove the recurring decimal, convert it to a fraction by putting the recurring digit(s) as the numerator over a denominator of the same number of 9s and reducing the fraction to its lowest terms.

Examples

- 0.333333333...

0.3333333... as a fraction: repeating digit is 3 so put as the numerator over a denominator of one 9 to give the fraction 3/9 = 1/3

So 0.333333333... = 33 1/3 %

- 0.1428571428...

0.28571428... as a fraction: repeating digits are 285714 of which there are six, so put as numerator over a denominator of six 9s to give the fraction 285714/999999 = 2/7

So 0.1428571428... = 14 2/7 %
