To be able to add fractions with different
Denominators, you must rename them so
that they have the same Denominators. To
do that you have to find the Least Common
Multiple (LCM). Also call the LCD Lowest
common denaminator.

6 is lowest multiple of these two
fraction, because 6 is smallest
number that divides evenly into 2
and 3.
