To find the difference between 8.76 and 26.54 using the additive inverse, we need to change the sign of one of the numbers and then add them together.
We can change the sign of 26.54 by multiplying it by -1:
-1 * 26.54 = -26.54
Now we can add 8.76 and -26.54:
8.76 + (-26.54) = -17.78
Therefore, 8.76 - 26.54 = -17.78.
Use the additive inverse to find 8.76−26.54

To find the difference between -1223 and -856 using the additive inverse, we need to change the sign of the second number and then add them together.
We can change the sign of -856 by multiplying it by -1:
-1 * -856 = 856
Now we can add -1223 and 856:
-1223 + 856 = -367
Therefore, -1223 - (-856) = -367.
To write this as a mixed number, we need to express it as a whole number and a proper fraction.
Since -367 is negative, we will write it as - (3 * 100 + 67).
So, -367 can be written as -3 and 67/100.
Therefore, -1223 - (-856) = -3 67/100.
