Answer 3

what is −12 2/3 − (−8 5/6) as a mixed number

Answer 4

To find the additive inverse of a number, we change the sign of the number.

The additive inverse of -856 is 856.

Now we can subtract -856 from -1223:

-1223 - (-856) = -1223 + 856

To add these two numbers, we align them vertically and add the corresponding place values:

```
-1223
+ 856
-------
```

Starting from the rightmost column, we have:

3 + 6 = 9
2 + 5 = 7
2 + 8 = 10

Write down the 0 and carry over the 1:

1 + 1 = 2

Adding all the column values, we have:

```
-1223
+ 856
-------
367
```

Therefore, -1223 - (-856) = 367.

The answer as a mixed number is: 367
