Answer: To find the lowest common denominator (LCD) of 5/6 and 3/4, we need to determine the smallest multiple that both 6 and 4 share. We can do this by listing the multiples of 6 and 4 and finding the smallest one they have in common:
Multiples of 6: 6, 12, 18, 24, 30, 36, ...
Multiples of 4: 4, 8, 12, 16, 20, 24, ...
From the lists above, we see that 12 is the smallest multiple that both 6 and 4 share. Therefore, the LCD of 5/6 and 3/4 is 12.
Answer: B. 12
