O-42
O -28
O 28
O42

The best estimate for the given calculation is 2.8.

Step-by-step explanation:

To determine the correct option regarding the result of this calculation, the mathematical resolution of the same must be developed:

-14 x 1 /9 x (-2 x 9/10) = X

-14 x 1 / 9 x (-18 / 10) = X

-14 x 1 / 9 x -1.8 = X

-14 / 9 x -1.8 = X

-1.555555 x -1.8 = X

2.8 = X

Therefore, the best estimate result for this mathematical operation is 2.8.
