First, let's simplify the expression step by step:
4 5/6 can be converted to an improper fraction:4 * 6 + 5 = 24 + 5 = 29/6
(29/6 - 2.5) 12 = (29/6 - 5/2) 12 = (58/12 - 30/12) 12 = 28/12 12 = 28
Now, we have: 28 - 28 * 5/9
28 * 5/9 = 140/9
Finally, 28 - 140/9 = 252/9 - 140/9 = 112/9
Therefore, the final result of the expression (4 5/6-2.5)×12-28×5/9 is 112/9 or 12 4/9.
