For example, the numerators of fractions with common denominators can simply be added, such that 5 12 + 6 12 = 11 12 (\ displaystyle (\ frac (5) (12)) + (\ frac (6) (12)) = (\ frac (11) (12))) and that 5 12 <11 12 (\ displaystyle (\ frac (5) (12)) <(\ frac (11) (12))), since each fraction has the common denominator 12 . Without computing a common denominator, it is not obvious as to what 5 12 + 11 18 (\ displaystyle (\ frac (5) (12)) + (\ frac (11) (18))) equals, or whether 5 12 (\ displaystyle (\ frac (5) (12))) is greater than or less than 11 18 (\ displaystyle (\ frac (11) (18))). Any common denominator will do, but usually the lowest common denominator is desirable because it makes the rest of the calculation as simple as possible . </P> <P> The expression "lowest common denominator" is used to describe (usually in a disapproving manner) a rule, proposal, opinion, or media that is deliberately simplified so as to appeal to the largest possible number of people . </P>

The least common denominator is the least common multiple of the blank of the fractions answer
