Answer 1

4, 8, and 3 must all go into the number. find the LCM(4,8) is 8. the LCM(8,3) is 24. that's your answer, 24

Answer 2

Analyze the 3 given denominators:

4 = 2*2

8 = 2*2*2

3 = 3

The three 2's that make up 8 are part of the LCD; the other part is the 3. Thus, your LCD is 24. Thus, 9/4= 54/24; 3/8 = 9/24; and 1/3 = 8/24.
