Hello all, im sorry for stealing this topic, but i ran into a problem on the exact same page, but my only problem is how come
So, same exact example. (i dont know how to do the points above the 18 to signify the repeating 18's. so ill just use the three dots to signfy repeating, even if its a little false).
100*0.18... = 18.18...
Subtracting .18... from both sides yields
100 * 0.18.. - 0.18... = 18.18... - .18...
that is
99 * .018... = 18.0
what? 0.18...-100 != 99 Where does the 99 come from? I see from the next few examples that it always seems to be 1000-0.0315... = 999. So i figure i could go ahead and just always go down one integer and be fine, but i want to understand it, if i dont understand, the chances of forgetting it are infinitely larger!
Anyway, thanks again, sorry for bad formatting of the numbers, and sorry for hijacking the thread.
