7/11

Explanation:

We let 0.63 (63 being repeated) be x.

x = 0.6363...

Since x is recurring in 2 decimal places, we multiply it by 100.

100x = 63.6363...

Next, we subtract them.

100x - x = 63.6363... - 0.6363...

99x = 63

The recurring digits '63' cancel off and the result is that 99x is non-recurring.

Lastly, we divide both sides by 99 to get x as a fraction.

x = 63/99

= 7/11

Therefore,

0.6363... = 7/11
