A Maths Puzzle...

[darius8]

a repeating decimal is a RATIONAL number.

it is rational because it can be written as the ratio of two integers...

in this case,eg, 999/1000= .999 or 99,999/100,000=.99999

Ahh. Your right! I got confused with nonterminating/ nonrepeating decimals such as pi and "golden ratio". It's been awhile since algebra.

I kid, I kid. I say this as one who is terrified of math.

I still like the version in base 9:

1/3 = 0.3

0.3 * 3 = 1

Simples.
