Only connection that I know is both are divisible by 3 and both are 9 integers apart from each other on the number line.desiguy wrote:whats the connection between 12 and 21 ?

how ?
Also
12/21 = 4/7 if you subtract 3 from numerator and denominator you will get 1/3
OK now seriously this cant be a question. There is something definitely wrong with it.

That's cause the FULL question is not typed out. The "connection" is actually a defined in the problem as something like "the lowest common multiple of both integers divided by their products". I know this question because it's been posted here so many times.parallel_chase wrote: OK now seriously this cant be a question. There is something definitely wrong with it.
Seriously? Have the decency to write out the full question if you want help with your problems.

Yes, most of the question is in fact missing.
This is a "wacky definition" question, in which the term "connection" is defined solely for the purpose of this particular question. Without the definition, there is no possible way to answer the question.

Is there such a question that exists on the actual GMAT or in OG material? If so I would be interested in reading it. I have seen question that ask about Fermat primes, but that is not a made up concept.

The 'connection' is actually not a made up concept either; it's just not very useful, since it's always equal to the reciprocal of the GCD (because the LCM*GCD = Product). The GMAT question that immediately comes to mind in this vein is the question about the 'length' of an integer, and if I recall correctly, that question is from GMATPrep- I might be wrong about that. The length, again, is a real math term,- it's interesting to see questions about Fermat Primes, lengths of integers, the golden ratio, etc- the questions are definitely prepared by mathematicians.gmatutor wrote:Is there such a question that exists on the actual GMAT or in OG material?
