Bill Best (kellyc@nbnet.nb.ca)  a reflechi et ecrit un jour:
: I am having problems with the following questions please explain this to 
: me.  0.099999999 as a fraction, 0.424242424242 as a fraction, 
: 0.3636363636363 as a fraction, 1.046464646464646 as a fraction.  Express 
: as entire radical 5 square root 8, 2 square root 3.  Expressed mixed 
: radical square root 32.

 Say x = 0.099999999
 So 10x = 0.999999999

Substract them, you have

9x = 0.9 so x = 0.9 / 9 = 9 / 90 = 1/10

Same for the others, maybe you'll have to multiply by 100 if there is
two periodic numbers.

If you know that sqrt(x) sqrt(y) = sqrt(xy) then you find

5 sqrt (8) = sqrt (25) sqrt(8) = sqrt(200)

And so on...

Luc.
