To simplify this expression, we first multiply the terms inside the parentheses:

(3/8 + 5/12) x 4 = (9/24 + 10/24) x 4 = 19/24 x 4 = 76/24 = 19/6

(5/6 - 2/9) ÷ 11 = (15/18 - 4/18) ÷ 11 = 11/18 ÷ 11 = 1/18

Now, we multiply the results from the two parentheses:

(19/6) x (1/18) = (19/6) ÷ (18/1) = 19/6 x 1/18 = 19/108

Therefore, the final answer is 19/108.
