Express the fractions 1/2, 3/16, and 7/8 with an lcd. a)8/16,3/16,14/16b)1/4,3/4,7/4c)1/3 2,3/32,7/32 d)1/32,3/32, 7/32 d)4/8,6/8,14/8

Answer is choice A



The LCD is 16

1/2 = (1/2)*(8/8) = 8/16
3/16 stays the same
7/8 = (7/8)*(2/2) = 14/16

So the list {1/2, 3/16, 7/8} is equivalent to the list {8/16, 3/16, 14/16}
