Use the additive inverse to find −123.45−(−234.76).(1 point) Responses 121.31 121.31 −358.21 negative 358.21 111.31 111.31 −111.31 negative 111.31

Answer 1

To find \(-123.45 - (-234.76)\), we can use the additive inverse.

The expression can be rewritten as:

\[ -123.45 + 234.76 \]

Now, we perform the addition:

\[ 234.76 - 123.45 \]

Calculating that:

1. Align the numbers:

   \[ 234.76 -123.45 \]

2. Subtract:

   Starting from the rightmost digits:

   • 6 - 5 = 1
   • 7 - 4 = 3
   • 4 - 3 = 1
   • 2 - 1 = 1
   • 0 (from 2 - 1) and 2 - 0 = 2 (we have borrowed nothing beyond this point)

Putting it all together, we get:

\[ 234.76 - 123.45 = 111.31 \]

So, the answer is:

\[ \boxed{111.31} \]
