I've always been pretty good with math in school, but school was a very long time ago and I got stumped on this question: if 3/4 of 3/8 equals 2, what is 1/4 of 3/8. I can't believe that I lost this much math ability but it has been almost 30 years ago since I was in college. Any help would be appreciated.

I think you mean: If 3/4 of 8/3 equals 2 then what is 1/4 of 8/3? We could write: You see, I think what they were after is that if 3/4 times some quantity is known, then 1/4 times that same quantity will be 1/3 of the original product, since 1/4 is 1/3 of 3/4.

Ummm...no it is not. Not trying to be obstinate. 3/4 of 3/8 is: However:

My sincerest apologies for my incorrect assumption. I simply felt it more likely that you recalled the problem incorrectly, simply inverting a fraction, rather than an application have such a basic and glaring error.

Any chance that it said: "If 3/4 of 3/8 OF X is 2..., what is 1/4 of 3/8 of X?" ??? (where X is some unknown) You could then solve for X and compute 1/4 of 3/8 of it. But 1/4 of 3/8 of anything is 1/3 of (3/4 of 3/8 of that thing, which equals 2). So we would get 1/3 of 2 = 2/3. Methinks.

No worries...my "ummm no" didn't make me look very nice either! St. Augustine is about 38 miles south of Jacksonville and 54 miles north of Daytona. So I am in NE FL. Fort Myers is in SW FL.
