答案： 解析：本题考查分数的四则运算。
答案为：
$\frac{8}{9} ÷ 8$
$= \frac{8}{9} × \frac{1}{8}$
$= \frac{1}{9}$
$\frac{7}{10} × \frac{5}{7}= \frac{1}{2}$
$\frac{7}{8} - \frac{3}{4}$
$= \frac{7}{8} - \frac{6}{8}$
$= \frac{1}{8}$
$\frac{2}{3} × \frac{2}{3}= \frac{4}{9}$
$\frac{2}{3} ÷ \frac{7}{6}$
$= \frac{2}{3} × \frac{6}{7}$
$= \frac{4}{7}$
$\frac{6}{7} + 7$
$= \frac{6}{7} + \frac{49}{7}$
$= \frac{55}{7}$
$= 7\frac{6}{7}$
$\frac{1}{3} × 27= 9$
$\frac{8}{3} ÷ \frac{8}{3}= 1$
$\frac{4}{5} × 3= \frac{12}{5}$
$= 2\frac{2}{5}$
$\frac{2}{5} × \frac{1}{2}= \frac{1}{5}$
$\frac{4}{5} - \frac{7}{10}$
$= \frac{8}{10} - \frac{7}{10}$
$= \frac{1}{10}$
$\frac{1}{4} + \frac{1}{3}$
$= \frac{3}{12} + \frac{4}{12}$
$= \frac{7}{12}$
$\frac{1}{4} × 8= 2$
$1 ÷ \frac{5}{7}$
$= 1 × \frac{7}{5}$
$= \frac{7}{5}$
$= 1\frac{2}{5}$
$\frac{1}{4} + 3$
$= \frac{1}{4} + \frac{12}{4}$
$= \frac{13}{4}$
$= 3\frac{1}{4}$
$24 ÷ \frac{2}{3}$
$= 24 × \frac{3}{2}$
$= 36$
$0 ÷ \frac{5}{6}= 0$
$6 ÷ \frac{2}{7}$
$= 6 × \frac{7}{2}$
$= 21$
$26 × \frac{12}{13}$
$= 2 × 12$
$= 24$
$\frac{5}{4} × \frac{12}{5}= 3$
$6 × \frac{1}{7}= \frac{6}{7}$
$\frac{21}{4} × \frac{4}{7}= 3$
