To simplify the expression \(-138.54 - (-245.9)\), we can use the property of additive inverses. The expression can be rewritten as:

\[ -138.54 + 245.9 \]

Next, we perform the addition:

  1. Combine the numbers: \[ 245.9 - 138.54 \]

  2. Calculate \(245.9 - 138.54\): \[ 245.9 - 138.54 = 107.36 \]

Therefore, the result of \(-138.54 - (-245.9)\) is \(107.36\).

The correct answer is:
