答案： 解析：这些题目都是基础的数学运算，包括分数的加减乘除以及与整数的混合运算。
答案：
$1 - \frac{1}{3} = \frac{2}{3}$
$\frac{5}{6} × \frac{2}{5} = \frac{1}{3}$
$9 ÷ \frac{3}{4} = 12$
$\frac{3}{8} ÷ 3 = \frac{1}{8}$
$\frac{2}{9} × \frac{3}{8} = \frac{1}{12}$
$36 × \frac{1}{2} = 18$
$\frac{5}{6} - \frac{2}{3} = \frac{1}{6}$
$\frac{1}{2} ÷ \frac{2}{5} = \frac{5}{4}$
$\frac{2}{13} ÷ 2 = \frac{1}{13}$
$\frac{5}{6} ÷ 5 = \frac{1}{6}$
$\frac{5}{24} × 8 = \frac{5}{3}$
$\frac{5}{9} × 27 = 15$
$\frac{5}{2} ÷ 5 = \frac{1}{2}$
$26 × \frac{1}{2} = 13$
$\frac{5}{12} × 18 = \frac{15}{2}$
$\frac{6}{7}× 3 = \frac{18}{7}$
$\frac{7}{6} × \frac{5}{3} = \frac{35}{18}$
$\frac{4}{5} × 3 = \frac{12}{5}$
$\frac{1}{2} ÷ \frac{1}{3} = \frac{3}{2}$
$\frac{6}{5} - \frac{7}{10} = \frac{1}{2}$
$\frac{4}{5} ÷ \frac{1}{2} = \frac{8}{5}$
$\frac{9}{8} - \frac{3}{4} = \frac{3}{8}$
$\frac{8}{9} ÷ 4 = \frac{2}{9}$
$\frac{2}{3} ÷ \frac{15}{16} = \frac{32}{45}$
