Answer:
Notice that all of the tiles that cover 12 and 13 have something in common: Their denominators are common multiples of 2 and 3 , the denominators of 12 and 13 . The least common multiple (LCM) of the denominators is 6 , and so we say that 6 is the least common denominator (LCD) of the fractions 12 and 13 .
