does anyone know of a good algorithm to compare fractions, eg 1/2 < 1/8 ?
you can convert the fractions to float and then compare but i would like to avoid that.

Convert to common denominator. Quickest and easiest way is to just multiply by opposite denominators:

So 1/2 < 1/8 ~~ 8 < 2 (sixteenths)
Or 3/7 < 2/5 ~~ 15 < 14 (thirty-fifths)

Or did I misunderstand?

I can relate. I hate it when I get so detailed that I miss the obvious.

I'm curious - how do you store the fractions, and what advantage in using them?

BTW, this sort of thing is not uncommon in my home ..

Later:

YD: So did you come up with a solution?
Me: Yes.
YD: What?
Me: *reluctant* I pressed the start button.
