No, it means `based on reason'. The OED gives no evidence of the word
ever having commonly used to mean `measure or proportion'.


from [L.]; ratio]

Yes, from the Latin `ratio', meaning `reason' or `computation'.
Subsequently, the word `ratio' in English has come to mean the
proportion of two numbers. But English is not Latin: the Latin
meaning of a word is nothing more than a hint as to the English
meaning of the same sequence of letters.

Why don't you try consulting a dictionary from time to time? Talking
with people would be so much easier if you used the same definitions
as the rest of us. As it is, you're apt to spend a great deal of time
trying to convince us that it's a good idea to eat arsenic and then
you find that we're disagreeing with you because we do not use the
word `arsenic' to refer to some variety of chocolate eclair.
