(9 - 2 2/15) (3 1/12) = (9 - 32/15) (37/12)

To subtract the mixed number (2 2/15) from 9, convert it to an improper fraction:
2 2/15 = (2*15 + 2) / 15 = 32 / 15

So, (9 - 32/15) = (135/15 - 32/15) = 103/15

Now, simplify the expression:
(103/15) (37/12) = (103 37) / (15 * 12) = 3811 / 180

Finally, multiply by 9/14:
(3811/180) (9/14) = (3811 9) / (180 * 14) = 34299 / 2520

Therefore, (9 - 2 2/15 3 1/12) 9/ 14 = 34299/2520 or approximately 13.6068
