Answer is 83/99.
0.83 repeating as a fraction, step by step.
The decimal (.83) times the percent based on the number of decimal places in the repeat, in this case it’s 2 places, so (100), subtract the non repeating part of the decimal (there is none so (0), divided by 9 if one repeating number, 99 if two repeating numbers, 999 if three repeating numbers, etc. in this case it is (99).
(0.83 x 100) - 0 / 99 = 83/99
