A. 12; Least common denominator is the least multiple that the denominator have together. So you multiply the denominators until you get the first number they both have in common.
6*1 = 6
6*2 =12
4*1 =4
4*2 =8
4*3 = 12
Since the first number they both have in common is 12, the least common denominator is 12
