To solve this expression, we will perform the operations in order of operations (parentheses, exponents, multiplication/division, addition/subtraction) and simplify as we go along.
First, we'll simplify the expressions within the parentheses:
-1 11/20 = -1.55
Now we have:
(1.9 - 5):(-1.55) + 4.8:(-16.67)
Next, we'll perform the division:
-3.1:-1.55 + 4.8:-16.67
Finally, we'll perform the division:
2 + (-0.288)
So, the final answer is 1.712.
