It's all to do with expressing recurring numbers as fractions - for example people often say 1/3 is 0.3, but if you multiply 0.3 by three, you get 0.9 whereas 1/3 multiplied by 3 is 1. so it is impossible to divide 1 by 3 in decimal form. yes?

i'm an online gamer, and about 8 months back, someone sent me a copy of 'SpeederXP' a RAM hacker - I tried it and I was warping so much , i couldnt shoot straight - god knows how it works, but after about 5 mins gameplay i gave that up

ok, i'm new here, so i thought i'd show you something neat but first of all, my notation - when I mean a number is recurring (going on forever, the recurring part will be in bold. (for example - 0.9 means 0.9999999... 0.42 means 0.4242424242... and 0.4567 means 0.4567567567...) if you wish to express a number as a fraction, you can use this simple trick: 0.43 as a fraction: first call the number I so I = 0.43 therefore 100I = 43.43 if 100I - I = 99I, and 100I - I = 43.43 - 0.43 = 43, then 99I = 43 /99, and I = 43/99! nice! well, here's the neat part: say we wanted to express 0.9 so, 0.9 as a fraction: first call the number I so I = 0.9 therefore 100I = 99.9 if 100I - I = 99I, and 100I - I = 99.9 - 0.9 = 99, then 99I = 99 /99, and I = 1 so 0.9 = 1 discuss.
