It depends how many unique integers you have in the decimals, and when the recurring starts
Like say you had 8.888888
To get rid of the recurring, you only need
10x = 88.88888
So 9x = 80
However, say you had 4.565656
10x wont work here, it would only mess up the decimals (you can try it yourself to see)
So you get 100x = 456.565656
So 99x = 452
It also depends when the recurring starts, so say you had
4.4676767
You need 1000x as 4467.676767, so you can isolate the recurring again
And also 10x, not x, as 10x = 44.676767, again isolating the recurring - if you used x, this would again mess up the decimels and not cancel out the recurring when you subtract them
Then you can get 990x as 4427, and then proceed as usual again

Doesn’t Matter 100x will still have .88888
You’ll just have 99x = 88
X=88/99
divide by 11
X=8/9

For every recurring decimal multiply by an extra 0
