A)4
B)12
C)3
D)8

Answer 1

The least common denominator of 3/4 and 3/8 is 8.

Step-by-step explanation:

To find the least common denominator (LCD) of 3/4 and 3/8, we need to find the smallest number that both 4 and 8 can divide into evenly. First, we can list the multiples of 4 and 8:

1. 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, ...
2. 8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, ...

We can see that the least common multiple (LCM) of 4 and 8 is 8. Therefore, the least common denominator (LCD) of 3/4 and 3/8 is 8 (option D).
