Stupid schematic-reading question

[Berry R. Thrailkill]

   I've been mostly lurking on this list for a while.  I'm fairly new to
electronics in general, so this might be a stupid question; if it is I
apologize in advance.

   I hope this is considered on-topic:

   I've been looking over some old Roland schematics (202/303/606/808)
with the intention of (possibly) building my own versions of these
instruments and using these designs as learning tools for eventually
designing my own equipment.

   The schematics themselves are actually pretty simple, but I've got a
bit of a problem with the capacitor values.  Some of the values are just
numbers without values; I'm assuming these are microfarads but I'm not
sure.  Others are expressed as a number, a slash, and then another number;
kind of like a fraction, except I don't think the numbers make sense as
capacitor values.  (e.g. 10/16, 1/50, 47/16, .47/50, 33/6.3)

   I've checked all the electronics books I can find (admittedly, not
many) and none of them have any information on this notation for capacitor
values.  I'm completely stumped on this one, people.  I'll greatly
appreciate any help you can give me.

   Thanks in advance, everyone. :)
