Answer 2

To simplify the given expression:

• Subtract the second value within each set of parentheses from the first value within each set.
• Then, subtract the result of the first set of parentheses from the result of the second set of parentheses.
• Finally, negate the final result.

Let's calculate it step by step:

1. Subtract the values within the first set of parentheses:

   • (10.77 - 6 2/9) = 10.77 - 6.2222... = 4.5478...

2. Subtract the values within the second set of parentheses:

   • (0.23 - 2 7/9) = 0.23 - 2.7777... = -2.5477...

3. Now, subtract the result from the second set of parentheses from the result of the first set of parentheses:

   • 4.5478... - (-2.5477...) = 4.5478... + 2.5477... = 7.0955...

4. Finally, negate the result:

   • -(7.0955...) = -7.0955...

So, the final result of the expression is approximately -7.0955...
