答案： 解析：本题考查分数的乘除法。
答案为：
$\frac{6}{9} ÷ 6$
$= \frac{6}{9} × \frac{1}{6}$
$= \frac{1}{9}$
$\frac{3}{4} × \frac{4}{3} = 1$
$\frac{4}{3} ÷ \frac{8}{7}$
$= \frac{4}{3} × \frac{7}{8}$
$= \frac{7}{6}$
$\frac{3}{4} ÷ \frac{4}{3}$
$= \frac{3}{4} × \frac{3}{4}$
$= \frac{9}{16}$
$\frac{2}{3} ÷ \frac{3}{2}$
$= \frac{2}{3} × \frac{2}{3}$
$= \frac{4}{9}$
$\frac{1}{6} ÷ \frac{1}{18}$
$= \frac{1}{6} × 18$
$= 3$
$0 ÷ \frac{1}{4} = 0$
$\frac{3}{5} × \frac{5}{6} = \frac{1}{2}$
$3 ÷ \frac{3}{7}$
$= 3 × \frac{7}{3}$
$= 7$
$\frac{3}{5} ÷ \frac{5}{6}$
$= \frac{3}{5} × \frac{6}{5}$
$= \frac{18}{25}$
$\frac{5}{7} ÷ \frac{3}{7}$
$= \frac{5}{7} × \frac{7}{3}$
$= \frac{5}{3}$
$\frac{4}{7} ÷ \frac{1}{5}$
$= \frac{4}{7} × 5$
$= \frac{20}{7}$
$\frac{1}{16} ÷ \frac{1}{8}$
$= \frac{1}{16} × 8$
$= \frac{1}{2}$
$\frac{5}{6} × \frac{1}{3} = \frac{5}{18}$
$\frac{3}{16} ÷ \frac{1}{3}$
$= \frac{3}{16} × 3$
$= \frac{9}{16}$
$\frac{5}{6} ÷ \frac{1}{3}$
$= \frac{5}{6} × 3$
$= \frac{5}{2}$
$\frac{1}{9} ÷ \frac{1}{4}$
$= \frac{1}{9} × 4$
$= \frac{4}{9}$
$\frac{4}{9} × \frac{3}{4} = \frac{1}{3}$
$\frac{1}{7} ÷ \frac{1}{49}$
$= \frac{1}{7} × 49$
$= 7$
$\frac{4}{9} ÷ \frac{3}{4}$
$= \frac{4}{9} × \frac{4}{3}$
$= \frac{16}{27}$
