Which fraction is equal to 0.

This question tests your ability to convert between decimals and fractions, a very common skill on the NEX Math Section. Start by understanding the decimal value. The decimal 0.04 means four hundredths, which can be written as the fraction 4/100. The next step is to simplify this fraction by dividing both the numerator and the denominator by their greatest common factor, which is 2. Doing so gives 2/50. That fraction exactly matches option C, making it the correct answer. To verify, you can also convert 2/50 back into a decimal by dividing 2 by 50, which equals 0.04. The other options are incorrect because they represent much larger values. For example, 1/4 equals 0.25, 2/5 equals 0.4, and 2/500 equals 0.004. On the NEX exam, remembering that two decimal places correspond to hundredths can help you quickly form the correct fraction before simplifying.
