5. Proper fraction A proper fraction is when the numerator ( the top part of the fraction) is smaller than the denominator ( the bottom part of the fraction) 1/5 is a proper fraction because the numerator is smaller than the denominator. 9/10 is also a proper fraction because the numerator is smaller than the denominator.

18. Least common denominator Least common denominator is the smallest number that can be used for the bottom number of two or more different fractions.
