Use the additive inverse to find - 123.45 - (-234.76).
A. -111.31
B. -358.21
C. 111.31
D. 121.31
To find the value of -123.45 - (-234.76), we need to add the additive inverse of -234.76 to -123.45.
The additive inverse of -234.76 is 234.76 (since the additive inverse of a negative number is the positive number with the same absolute value).
So, -123.45 - (-234.76) is equal to -123.45 + 234.76.
Adding these two numbers, we get:
-123.45 + 234.76 = 111.31.
Therefore, the answer is:
C. 111.31
To find the solution to the expression -123.45 - (-234.76), we can use the concept of the additive inverse.
The additive inverse of a number is the number that, when added to the original number, gives a sum of zero.
To find the additive inverse of -234.76, we keep the sign but change its value. So, the additive inverse of -234.76 is 234.76.
Now we can rewrite the expression: -123.45 + 234.76
Adding these two values together, we get:
111.31
