This was a very hard one, since I'm not so good at math, I didn't really get it, but for the people who are good at math, they'll get it...EVENTUALLY.
This was not so difficult for me since I noticed the repeating digits in 'a' and 'e' and remembered my elementary & high school math. However, there is an error in answer g. The answer should be "066667" not "666667" which is 1/15 (0.066667) with the decimal point and leading zero removed, and rounded to 6 digits. "666667" would actually be 10/15 or 2/3.
my head hurts now, thanks
