[plt-scheme] Syntax for Maximum Number

There are many functions built into the teaching langauges for things
like that. One good way to find them is to guess at their names and
then use the interactions (bottom) window of DrScheme to see if you
guessed right. You can, of course, also search in Help Desk.

In this case, you want `max'. Here's some experimentation to give you an idea:

> (max 1 2)
2
> (max 223/457 678/983)
678/983
> (abs (- 223/457 678/983))
90637/449231
> (/ (floor (* 10 (abs (- 223/457 678/983)))) 10)
1/5
