The Question is:
ABCDEF is a 6-digit number. When it is multiplied by 3, the result is BCDEFA. When it is multiplied by 5, the result is FABCDE. What number is ABCDEF?
I'd be eternally grateful if you would help!!!!!! Thanks in advance!
help!!! This question is really really hard!

the first 6 digits of the fraction 1/7 (142857).
think about it
think about it
There was an open question which i have asked many proffesors and fellow mathematicians, but none were able to answer:
Is there a function f:R->R (not necessarily continuous on ALL of R) which:
for every linear function g(x)=m*x+n, there is a number X for which g is the tangent of f in? (for each x g(x)=f(X)+f'(X)(x-X))
i think not.
(i almost solved it - using a small set theory tweak and a big topology tweak)

the precentages in the poll thing sum up to 81% O.O

No it doesn't. It sums up to just above 100, which can be explained due to the rounding of fractions (100/15 < 7).
