One is with Yahoo. They turn the division symbol into a Hebrew
letter. Let me try again ºººººººººº
Second, my source that ratios should be treated as fractions comes
from a textbook. Page 274 in the "Scott Foresman - Addison Wesley"
Middle School Math, Course Two. I guess I can somehow scan the
book. I decided to see what wikipidia says.
http://en.wikipedia.org/wiki/Ratio
As far as the symbol itself is concerned, I am unsure as to what
symbol is the accepted form of typing up a symbol for a fraction or
division on a PC. I have seen in various forums where users have
used a slant symbol for both division and fractions. Then again,
users spell "great" as "gr8" and "you" as "u".

quote a reputable website?]
