To multiply \(-116\) by \(7\), we first perform the multiplication:
\[ -116 \times 7 = -812 \]
A mixed number consists of an integer and a proper fraction. Since \(-812\) is a whole number, we can express it as a mixed number by writing it as:
\[ -812 = -812 \frac{0}{1} \]
Thus, the answer as a mixed number is:
\[ -812 \frac{0}{1} \]
If you prefer to simply state the integer without the fraction, it can also be represented as just \(-812\).
