Umm, assuming in this case it would be 0.4646464646464646...
Then you would just assign it a variable in the beginning:
x = 0.46464646...
Then multiply it by 100, to get:
100x = 46.46464646464646...
Now you just want to subtract x from 100x, or
46.464646464646464646... - 0.46464646464646...
Which would result in 99x = 46.
Now just divide 99 from both sides to get:
x = 46/99
So it would be 46/99.
I think.
