Shit, of course:

1) 0 < 1 - c/d < 1
2) -1 < - c/d <0> c/d > 0

I make a mistake in the beginning in subtracting 1 (I added 1 =)).
I should be more focused =)

here,

from the second inequality,

-1<-c/d<0>c/d>0

since c/d>0, and d>0, c>0 -------I st
c/d<1, obviously-------------------II st

now for the third it depends, if both c and d are intengers then the III is true, however both c and d may be ratios (c=1/4, d=1/2), then III statement is not true.

Thanks! =)

whenever i use <> sings HTML changes the text...

I and II

III may not be possible if say d=0.5 and c=0.4.
