I can't quite remember what the Egyptians did, anyway. I must get a
copy of Ifrah's _Universal History of Numbers_. Anyhow, I _think_
they didn't really understand the idea of a fraction as a ratio of two
numbers - they knew about halves, and could apply them iteratively,
but they lacked the concept (or at least the notation) to express
something like 5/18. I could be wrong about this, though - it was
something I read a while ago. Well, I might as well look it up before
posting this...

I have that book! But I'm not too sure where in the house it is :D
All I remember from it about Egyptian fractions though is that they
took the components of the eye of Horus as symbols for fractions 1/2,
1/4, 1/8, 1/16, 1/32 and 1/64...
