To calculate this expression, we first need to convert the mixed numbers into improper fractions.
1 2/9 = 11/91 1/6 = 7/61 25/42 = 67/42
Now we can calculate:
(11/9 + 7/6) (2 - 67/42)= (22/18 + 21/18) (84/42 - 67/42)= (43/18) (17/42)= (43/18) (17/42)= 731/756
Therefore, the result is 731/756.

1 25/42 = 67/42
Now we can calculate:
(11/9 + 7/6) (2 - 67/42)
= (22/18 + 21/18) (84/42 - 67/42)
= (43/18) (17/42)
= (43/18) (17/42)
= 731/756
Therefore, the result is 731/756.
