\(1\frac{1}{3}\div1\frac{1}{4}\div1\frac{1}{5}\div1\frac{1}{6}\div1\frac{1}{7}\div1\frac{1}{8}\)
\(=\frac{4}{3}\div\frac{5}{4}\div\frac{6}{5}\div\frac{7}{6}\div\frac{8}{7}\div\frac{9}{8}\)
\(=\frac{4}{3}\times\frac{4}{5}\times\frac{5}{6}\times\frac{6}{7}\times\frac{7}{8}\times\frac{8}{9}\)
\(=\frac{16}{27}\)
