To add the numbers \(-127\) and \(314\), we proceed as follows:
- Calculate the sum:
\[ -127 + 314 = 314 - 127 \]
- Perform the subtraction:
\[ 314 - 127 = 187 \]
So, the result of adding \(-127\) and \(314\) is \(187\).
Next, to express \(187\) as a reduced improper fraction, we can write it as:
\[ \frac{187}{1} \]
Thus, the final answer is:
\[ \boxed{\frac{187}{1}} \]
