答案： 解析：这些题目都是基础的分数除法运算，需要掌握分数除法的运算规则，即“除以一个分数等于乘以这个分数的倒数”。
答案：
$12 ÷ \frac{1}{3} = 36$
$100 ÷ \frac{1}{3} = 300$
$10 ÷ \frac{5}{8} = 16$
$8 ÷ \frac{2}{3} = 12$
$\frac{1}{3} ÷ 4 = \frac{1}{12}$
$12 ÷ \frac{1}{6} = 72$
$12 ÷ \frac{1}{4} = 48$
$10 ÷ \frac{5}{15} = 30$
$10 ÷ \frac{5}{7} = 14$
$24 ÷ \frac{4}{3} = 18$
$\frac{1}{2} ÷ \frac{2}{3} = \frac{3}{4}$
$10 ÷ \frac{3}{4} = \frac{40}{3}$
$12 ÷ \frac{3}{4} = 16$
$12 ÷ \frac{5}{4} = \frac{48}{5}$
$28 ÷ \frac{14}{3} = 6$
$28 ÷ \frac{7}{5} = 20$
$\frac{8}{9} ÷ \frac{8}{9} = 1$
$5 ÷ \frac{5}{6} = 6$
$12 ÷ \frac{4}{3} = 9$
$\frac{2}{3} ÷ \frac{2}{3} = 1$
$\frac{3}{5} ÷ \frac{9}{10} = \frac{2}{3}$
$\frac{1}{4} ÷ \frac{1}{2} = \frac{1}{2}$
