Exotic fraction

[Renato]

A [fraction] that you might have to deal with when doing a college-level homework problem. It doesnt necessarily have to contain X or any other variable, but it does have to have to be a numerator-denominator combination that you would not normally see in everyday life. The reason the number is written as a fraction is because writing it as a [decimal] would require imprecise [rounding] off and/or because it must be added, subtracted, or multiplied with a similar fraction.
