Well, isn't that just a lovely repeating decimal we have there. Let's turn that into a fraction, shall we? If we call x = 0.7777777, then 10x = 7.7777777. Now, if we subtract x from 10x, we get 9x = 7, which simplifies to x = 7/9. And there you have it, a beautiful fraction created from a repeating decimal.
