To find \( 23.45 - 68.7 \) using the additive inverse, you rewrite the subtraction as follows:
\[
23.45 + (-68.7)
\]
Now, to add these two numbers, we note that \(-68.7\) is the additive inverse of \(68.7\).
To perform the addition, we first find the absolute values:
1. Calculate \( 68.7 - 23.45 \):
\[
68.7 - 23.45 = 45.25
\]
Since \(68.7\) is larger than \(23.45\), the result will be negative:
\[
23.45 - 68.7 = -45.25
\]
Thus, the answer is:
**B. −45.25**
\[
23.45 + (-68.7)
\]
