To solve and simplify \( 810 - 710 \):
First, perform the subtraction: \[ 810 - 710 = 100 \]
Now, let's look at the response options given. Since 100 does not appear directly, it is possible that we are asked to express 100 in fraction form.
To express 100 as a fraction, we can write: \[ 100 = \frac{100}{1} \]
However, if we want to convert it to a form that matches some of the given options, let’s see if we can express 100 in terms of fractions that are close to the options provided. For simplicity, if we divide the fraction \( \frac{100}{1} \) by 10, this gives us: \[ \frac{100}{1} = \frac{1000}{10} \]
However, none of the responses match this representation. As I've interpreted the question, the question seems to expect one of the simpler fractions:
- \( \frac{1}{20} \)
- \( -\frac{1}{10} \)
- \( \frac{1}{10} \)
- \( \frac{3}{2} \)
Since none of these options is equal to 100, the direct subtraction yields a solution of \( 100 \).
If you were looking for a choice that is less obvious in the context, it might be that 100 is considered off while the numbers were supposed to be closer approximations such as a percentage or decimal which isn’t applied here based on the options provided.
Therefore, the answer is: \[ \text{None of the provided options } (120, , -110, , 110, , 32) \text{ fit } 100. \] If possible, confirm if the subtraction needed another interpretation or if this was meant to correspond more closely to the responses listed separated from their configurations.
