To solve this expression, we need to simplify it step by step:
First, simplify the expressions inside the parentheses:(-2/3 + 6.4/5) = (-2/3 + 1.28) = -0.6666667 + 1.28 ≈ 0.6133333(-5/6 - 2.3) = (-5/6 - 2.3) = -0.8333333 + (-2.3) ≈ -3.1333333
Now add the simplified expressions:0.6133333 + (-3.1333333) = -2.52
Therefore, the result of the expression (-2/3 + 6.4/5) + (-5/6 - 2.3) is approximately -2.52.
