I want to know the approach for the following kind of questions:

Which of the following numbers if the greatest?
A) 1876452/1876455
B) 1883446/1886449
C) 1883453/1883156
D) 1883456/1883459
E) 1883491/1883494[/list][/list]

Replying a query takes patience and time. The least a person can do is to thank the reply.

C is the only one with a numerator greater than its denominator, so it must be the biggest number.

In general, when a question gives you values that you can't easily calculate, you should look to apply your knowledge of number properties and basic rules. If all 5 answers had given us fractions where the denominator was greater than the numerator, finding the difference between the terms and trying to extract a pattern or rule would be helpful.

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
