3a - b / 9 - (a - 2b / 3) - (4a - 3b/6)
= [3a - a - 4a] - b/9 + 2b / 3 + 3b / 6
= -2a - 2b / 18 + 12b / 18 + 9b / 18
= -2a + 19b / 18

(3a-b/9) - (a-2b/3) - (4a-3b/6)
[2(3a-b) -6(a-2b) - 3(4a-3b)]/ 18
(6a -2b - 6a + 12b - 12a + 9b)/ 18
(-12a + 19b)/ 18

(3a-b/9) -(a-2b/3)-(4a-3b/6) =
[3a-a-4a]-b/9+2b/3+3b/6=
-2a-2b/18+12b/18+9b/18=
-2a+19b/18

= (6a-2b -6a+12b - 12a +9b)/18 = (-12a+19b)/18
