答案： 解析：本题主要考查分数的四则运算，包括乘法、除法和减法，需要掌握分数的运算规则。
答案：
$0×\frac{1}{7}= 0$
$\frac{2}{3}×\frac{1}{2}= \frac{1}{3}$
$\frac{4}{5}-\frac{1}{2}= \frac{3}{10}$
$\frac{5}{6}×\frac{7}{8}= \frac{35}{48}$
$\frac{8}{9}×\frac{15}{16}= \frac{5}{6}$
$\frac{1}{2}÷\frac{1}{8}= 4$
$\frac{8}{9}-\frac{1}{9}= \frac{7}{9}$
$\frac{4}{5}×\frac{2}{6}= \frac{4}{15}$
$\frac{1}{7}×\frac{14}{5}= \frac{2}{5}$
$3×\frac{7}{12}= \frac{7}{4}$
$\frac{2}{9}×\frac{3}{6}= \frac{1}{9}$
$\frac{5}{6}-\frac{1}{3}= \frac{1}{2}$
$1-\frac{2}{3}= \frac{1}{3}$
$9÷\frac{3}{4}= 12$
$\frac{1}{3}÷4= \frac{1}{12}$
$5÷\frac{5}{3}= 3$
$6×\frac{2}{3}= 4$
$\frac{4}{9}×\frac{3}{8}= \frac{1}{6}$
$\frac{7}{12}-\frac{1}{4}= \frac{1}{3}$
$\frac{5}{9}-\frac{1}{3}= \frac{2}{9}$
