Use the additive inverse to find −1223−(−856). Write the answer as a mixed number.(1 point)
The additive inverse of a number is its opposite.
To find the sum of -1223 and -(-856), we can rewrite the expression as -1223 + 856.
Now, we can add the two numbers together:
-1223 + 856 = -367.
Therefore, -1223 - (-856) is equal to -367.
To write the answer as a mixed number, we divide -367 by 1.
So, -367 can be written as -367/1.
Therefore, the answer is -367/1.
To find the additive inverse of a number, we simply change the sign of the number.
The additive inverse of -856 is 856.
To solve -1223 - (-856), we can rewrite it as -1223 + 856.
(-1223) + 856 = -367.
Therefore, the answer is -367, which can also be written as a mixed number as -367/1.
