Help our community expand it. +Fractions of integers can be classified as either proper or improper, though this distinction has no effect mathematically on how to [add/multiply/use](https://github.com/freeCodeCamp/freeCodeCamp/blob/master/guide/english/mathematics/fractions/index.md) them. -This quick style guide will help ensure your pull request gets accepted. - - - -#### More Information: - +If we have a fraction a/b, where a and b are integers and b is not 0, then when a < b or |a| < |b| we say the fraction is *proper*. All other fractions are called *improper*. +For example, 1/2, 2/3, 3/5 and -6/17 are all proper fractions, while 1/1, 3/2, -4/3 and 99/3 are all improper fractions. +The term likely originates from the original use of fractions to be [part of a whole](http://mathforum.org/library/drmath/view/70437.html) and improper fractions are the generalization to this notion.
