To solve the expression \( 810 - 710 \), you can subtract directly:
\[ 810 - 710 = 100 \]
Now, let's look at the options provided for simplification:
- 110
- \(\frac{1}{10}\)
- 32
- \(\frac{3}{2}\)
- 120
- \(\frac{1}{20}\)
- -110
Since \( 100 \) is not listed as an option, it doesn't appear to be included in your responses. However, the calculation is correct; the answer is \( 100 \).
If there is some other context or information required to match to the answers provided, please clarify.
