I gave this lesson one time. In a community college.

Hi again all,

I realized that the previous post is not very good. 1/5 + 4/5 = 1 is true and 0.2 + 0.8 = 1 is another way of saying the same thing. What I wanted is

4/9 + 5/9 = 1

This way we can see that

0.444 + 0.555 = 1

where there are an infinite number of 4 and 5 in the repeating decimals.
Then we have
0.999 = 1
And again 0.999 is an infinitely repeating decimal.

And that is the conclusion that I wanted.
Regards,
Matt
