To find the additive inverse of a number, we change the sign of the number. So, the additive inverse of -856 is 856.
To subtract -1223 from 856, we can rewrite the subtraction problem as addition by using the additive inverse. So, -1223 - (-856) becomes -1223 + 856.
-1223 + 856 = -367.
Therefore, the answer is -367.
Use the additive inverse to find −1223−(−856). Write the answer as a mixed number.(1 point

To find the additive inverse of a number, we change the sign of the number. So, the additive inverse of -8 5/6 is 8 5/6.
To subtract -12 2/3 from 8 5/6, we can rewrite the subtraction problem as addition by using the additive inverse. So, -12 2/3 - (-8 5/6) becomes -12 2/3 + 8 5/6.
To add these mixed numbers, we first need to find a common denominator, which in this case is 6.
(-12 2/3) * (6/6) = -78/6
(8 5/6) * (6/6) = 53/6
Now we can add the fractions:
-78/6 + 53/6 = -25/6.
When the fractions are added, it becomes evident that the numerator is negative, so we have a negative mixed number.
Since 25 is not divisible by 6, we can rewrite -25/6 in mixed number form:
-25/6 = -4 1/6.
Therefore, the answer is -4 1/6.
