Answer 2

To solve the given expression, let's break it down step by step:

1. Simplify the division inside the parentheses: - (-3/1) = -3

2. Simplify the division outside the parentheses: - (-19/3) = -6.3333 (rounded to four decimal places)

3. Substitute the simplified values back into the expression: - 127/14 - 2/7 - (-3) - 19/3 - (-19/27)

4. Perform the calculations in the expression: - 127/14 = 9.0714 (rounded to four decimal places) - 2/7 = 0.2857 (rounded to four decimal places) - -19/27 = -0.7037 (rounded to four decimal places)

Now the expression becomes: - 9.0714 - 0.2857 - (-3) - 19/3 - (-0.7037)

5. Simplify the expression further: - - (-3) = 3 - -0.7037 = 0.7037 (since the negative sign cancels out)

Now the expression becomes: - 9.0714 - 0.2857 + 3 - 19/3 + 0.7037

6. Perform the calculations: - 9.0714 - 0.2857 = 8.7857 (rounded to four decimal places) - 19/3 = 6.3333 (rounded to four decimal places)

Now the expression becomes: - 8.7857 + 3 - 6.3333 + 0.7037

7. Perform the final calculations: - 8.7857 + 3 = 11.7857 (rounded to four decimal places) - 11.7857 - 6.3333 = 5.4524 (rounded to four decimal places) - 5.4524 + 0.7037 = 6.1561 (rounded to four decimal places)

Therefore, the value of the given expression is approximately 6.1561.

Please note that the above calculations are rounded to four decimal places for simplicity.
