Answer 2

Let's break down the expression step by step:

1. First, we need to perform the division operation inside the parentheses:

   5 1/6 ÷ 1/2 = (5 1/6) ÷ (1/2) = (31/6) ÷ (1/2) = 31/6 * 2/1 = 62/6 = 10 1/3

   So, the expression inside the parentheses becomes:

   (2 3/4*4 + 10 1/3 - 10 5/9)*9

2. Next, we need to simplify the terms inside the parentheses:

   2 3/4 * 4 = (11/4) * 4 = 11

   10 1/3 - 10 5/9 = (31/3) - (95/9) = (93/9) - (95/9) = -2/9

   So, the expression inside the parentheses becomes:

   (11 - 2/9)*9

3. We can now simplify the expression inside the parentheses further:

   11 - 2/9 = (99/9) - (2/9) = 97/9

   So, the expression simplifies to:

   (97/9)*9

4. Finally, we can simplify the expression by canceling out the 9's:

   (97/9)*9 = 97

Therefore, the final answer is 97.
