1. (8 points) Calculate $\left[6 \frac{3}{5}-\left(8.5-\frac{1}{3}\right) \div 3.5\right] \times\left(2 \frac{5}{18}+\frac{11}{12}\right)=$
【Solution】Solve: $\left[6 \frac{3}{5}-\left(8.5-\frac{1}{3}\right) \div 3.5\right] \times\left(2 \frac{5}{18}+\frac{11}{12}\right)$,
$$
\begin{array}{l}
=\left[6 \frac{3}{5}-\frac{49}{6} \div 3.5\right] \times \frac{115}{36}, \\
=\left[6 \frac{3}{5}-\frac{7}{3}\right] \times \frac{115}{36}, \\
=\frac{64}{15} \times \frac{115}{36}, \\
=\frac{368}{27} ;
\end{array}
$$

Therefore, the answer is: $\frac{368}{27}$.
