We need to assume that =repeating decimal that is,
----(1)
Since, it is clearly visible that x is recurring in decimal places so we multiply by .
----(2)
Now, we subtract equation (1) from equation (2)
The repeating digits cancel off and we get left with being non-repeating.
Further, we divide left-hand side and right-hand side by
Here, we got in the form of a fraction. In order to simplify the fraction, we divide by .
Therefore, the answer is
Note: Don’t confuse (repeating) means Here in this question, we were given (repeating) which means both the digits are repeating and the bar is on both the digits.
