 Posted - 10/03/2007 :  20:07:08 afraid not.18/45 = (9 2)/(9 5)so, looking above, what is the GCF (greatest common factor) of the numerator and denominator?what will the fraction be in reduced terms?

 Posted - 10/04/2007 :  07:05:37 skeeter: You posted an excellent response!I wonder if wmdschristie3 meant GCF=18 (which would not be correct anyway) instead of GCF=81 (which makes no sense).wmdschristie3: How do you figure the GCF is 81? IF you meant 18, then yes, 18 does divide evenly into 18 but 18 does not divide evenly into 45.quote:Originally posted by skeeterafraid not.18/45 = (9 2)/(9 5)so, looking above, what is the GCF (greatest common factor) of the numerator and denominator?what will the fraction be in reduced terms?

 Posted - 10/04/2007 :  10:29:37 Since we are guessing what the problem could be.....Another possibility - the problem could have been:18/54 = 1/3 and GCF(18,54) = 18So two numbers transposed (54 to 45 and 18 to 81).
