fractions and calculus

One on the concepts students have the most trouble with is the concept
of ratio and proportion. If you don't understand what a ratio is and
can't see fractions as ratios you can't understand rate of change and
you can't do calculus.
Fractions are hard--they are ambiguous--they can represent division, ratios,
classes of quotients ((-4)^(1/3) makes sense in the reals but (-4)^(2/6)
doesn't). We have to keep teaching fractions and ratios. They prevade
all of mathematics. ....just my opinion...

Note: I think that it was said of Ramanujan that every number was his friend.
