To multiply \(-116\) by \(7\), we perform the following calculation:
\[ -116 \times 7 = -812 \]
Now, to express \(-812\) as a mixed number, we note that \(-812\) is a whole number and can be represented as a mixed number. However, since there is no fractional part, we can write:
\[ -812 = -812 \frac{0}{1} \]
Thus, the answer as a mixed number is:
\[ -812 \]
(with no fractional part).
