Answer:

8

Step-by-step explanation:

Note that 2 divides into 8 evenly, yielding the quotient 4.  8 is the LCD.  To combine 3/8 and 11/2, we would rewrite 11/2 as

4·11

------ = 44/8

 4·2

and then combine 44/8 with 3/8.  The sum would be 47/8.

In summary, the LCD of 3/8 and 11/2 is 8; 3/8 stays as is and 11/2 is rewritten by mult. numerator and denominator by 4 each.
