To solve this calculation, follow these steps:

Calculate 3/11 (-2/13) 9/33:
First, multiply 3/11 by -2/13: (3 -2) / (11 13) = -6 / 143
Then, multiply the result by 9/33: (-6/143) * (9/33) = -54 / 471

Calculate 5 1/2 (1/5 - 2):
First, convert 5 1/2 to an improper fraction: 5 1/2 = (25 + 1) / 2 = 11/2
Then, subtract 2 from 1/5: (1/5 - 2) = (1/5) - (10/5) = -9/5
Finally, multiply 11/2 by -9/5: (11/2) * (-9/5) = -99/10

Therefore, the final calculation is:
-54 / 471 and -99 / 10
