To solve the expression \( -123.45 - (-234.76) \) using the additive inverse, we can rewrite it as:

\[ -123.45 + 234.76 \]

Now, let's perform the addition:

\[ -123.45 + 234.76 = 234.76 - 123.45 \]

Calculating \( 234.76 - 123.45 \):

  1. Align the numbers by their decimal points:

    234.76
    -123.45
    
  2. Subtract the numbers:

    234.76
    -123.45
    ---------
    111.31
    

Thus, the answer is \( 111.31 \).

So the correct response is:

111.31
