I realise that was already said, but this shows how to get the solution to any problem.

First of all, a recurring digit is written like this x.(y)

but you cant represent with a fraction "numbers" that have two infinite periods (2 recurring parts) - 0.2(2)428571(1)

if the '2' repeats until infinity....there's no 'normal' mathematical way of representing [....]42857111111111111111111111111(1).... after that with a fraction.. Unless you invent a new kind of math ; )

Normal infinite periodic decimals are easy to convert into fractions.

It has a similar pattern to 1/7, which is 0.1428571428571... So I tried 0.2428571 x 7 = 1.7 And so the fraction would be 17/70 (Or 1.7/7, but it isn't right to mix decimals in fractions, so multiplying top and bottom by 10 fixes it)
