[SNIP]

Sorry, let's focus on the question at hand. I fear that your response
diverts from the issue I want clarified. (Once again, you've

By definition,

0.777... = sum_i=1^oo 7*10^-1.

You claim that 0.777... has a terminating decimal representation
(right?).

You accept the following definition:

Let x be a real number in [0,1].  We say that x has a terminating
decimal representation iff there is a natural number k and a
function f:{1,...,k} -> {0,...,9} such that

x = sum_i=1^k f(i) * 10^-i.

Therefore, I request a proof that there is a function

f:{1,...,k} -> {0,...,9}

such that

sum_i=1^k f(i)*10^-i = sum_i=1^oo 7*10^-i.

Unless you can prove that there is such a function, we must conclude
you have no proof that 0.777... is terminating.

Thanks much.
