In order to add or subtract fractions with different denominators (the bottom number of the fraction), you must first find the least common denominator shared between them. This refers to the lowest multiple shared by each original denominator in the equation, or the smallest whole number that can be divided by each denominator.<ref name="rf1">http://www.helpwithfractions.com/math-homework-helper/least-common-denominator/</ref> You may also see the phrase [[Find the Least Common Multiple of Two Numbers|least common multiple]]. This generally refers to whole numbers, but the methods to find it are the same for both. Determining the least common denominator allows you convert the denominators to the same number so you can then add and subtract them. | In order to add or subtract fractions with different denominators (the bottom number of the fraction), you must first find the least common denominator shared between them.
