Question

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)1/32,3/32,7/32 D)1/32,3/32, 7/32 D)4/8,6/8,14/8

Answer 1

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}

Answer 2

LCD is 16. So 1/2 becomes 8/16. 3/16 remains the same. 7/8 becomes 14/16.
