Answer 3

Let's simplify the expression using the order of operations (PEMDAS):

1. Solve the parentheses first:

   27/20 - 3/4 = 27/20 - 15/20 = 12/20 = 3/5

   9/11 * 8/9 = 8/11

2. Perform multiplication and division from left to right:

   6 * 2 1/2 = 6 * 5/2 = 15

   15 * 3/5 = 9

   4 8/9 * 8/11 = 44/9 * 8/11 = 352/99

3. Subtract from left to right:

   9 - 352/99 = (891/99) - (352/99) = 539/99

Therefore, the final result is 539/99, and it is not clear how the answer relates to the given score of 99 points.
