To solve the equation \(-9 = \frac{5}{6} t\), you can follow these steps:
- First, isolate \(t\) by multiplying both sides of the equation by the reciprocal of \(\frac{5}{6}\), which is \(\frac{6}{5}\):
\[ t = -9 \cdot \frac{6}{5} \]
- Calculate the right side:
\[ t = -\frac{54}{5} \]
- This can also be expressed as a mixed number:
\[ t = -10.8 \]
Thus, the solution is:
\[ t = -\frac{54}{5} \quad \text{or} \quad t = -10.8 \]
