1. Calculate:
$$
(0.5+0.25+0.125) \div(0.5 \times 0.25 \times 0.125) \times \frac{\frac{7}{18} \times \frac{9}{2}+\frac{1}{6}}{13 \frac{1}{3}-\frac{15}{4} \times \frac{16}{5}}
$$
$80 \frac{1}{2}$
1.【Solution】Original expression $=$
$$
\left(\frac{1}{2}+\frac{1}{4}+\frac{1}{8}\right) \div\left(\frac{1}{2} \times \frac{1}{4} \times \frac{1}{8}\right) \times \frac{\frac{7}{2} \times \frac{1}{2}+\frac{1}{6}}{13 \frac{1}{3}-3 \times 4}
$$
$$
\begin{array}{l}
=\left(\frac{1}{2}+\frac{1}{4}+\frac{1}{8}\right) \times 2 \times 4 \times 8 \times \frac{\frac{7}{4}+\frac{1}{6}}{13 \frac{1}{3}-12} \\
=(4+2+1) \times 2 \times 4 \times \frac{21}{\frac{12}{1}+\frac{2}{12}} \\
=7 \times 2 \times 4 \times \frac{23}{4 \times 4}=7 \times \frac{23}{2}=80 \frac{1}{2}
\end{array}
$$
