答案：
解析：本题主要考查分数的除法运算，根据分数除法的运算法则，除以一个分数等于乘以这个分数的倒数。
答案为：
$3 ÷ \frac{1}{4} = 3 × 4 = 12$；
$\frac{1}{10} ÷ \frac{2}{5} = \frac{1}{10} × \frac{5}{2} = \frac{1}{4}$；
$2 ÷ \frac{1}{3} = 2 × 3 = 6$；
$\frac{5}{12} ÷ \frac{1}{4} = \frac{5}{12} × 4 = \frac{5}{3}$；
$12 ÷ \frac{1}{2} = 12 × 2 = 24$；
$\frac{2}{7} ÷ \frac{2}{5} = \frac{2}{7} × \frac{5}{2} = \frac{5}{7}$；
$1 ÷ \frac{1}{8} = 1 × 8 = 8$；
$\frac{2}{3} ÷ \frac{6}{7} = \frac{2}{3} × \frac{7}{6} = \frac{7}{9}$；
$2 ÷ \frac{2}{3} = 2 × \frac{3}{2} = 3$；
$\frac{1}{6} ÷ \frac{1}{3} = \frac{1}{6} × 3 = \frac{1}{2}$；
$3 ÷ \frac{4}{7} = 3 × \frac{7}{4} = \frac{21}{4}$；
$\frac{2}{3} ÷ \frac{1}{2} = \frac{2}{3} × 2 = \frac{4}{3}$；
$4 ÷ \frac{4}{5} = 4 × \frac{5}{4} = 5$；
$\frac{1}{6} ÷ \frac{5}{6} = \frac{1}{6} × \frac{6}{5} = \frac{1}{5}$；
$6 ÷ \frac{6}{7} = 6 × \frac{7}{6} = 7$；
$\frac{3}{5} ÷ \frac{3}{4} = \frac{3}{5} × \frac{4}{3} = \frac{4}{5}$；
$9 ÷ \frac{3}{4} = 9 × \frac{4}{3} = 12$；
$\frac{1}{2} ÷ \frac{1}{4} = \frac{1}{2} × 4 = 2$；
$6 ÷ \frac{2}{3} = 6 × \frac{3}{2} = 9$；
$\frac{1}{5} ÷ \frac{1}{3} = \frac{1}{5} × 3 = \frac{3}{5}$；
$5 ÷ \frac{3}{5} = 5 × \frac{5}{3} = \frac{25}{3}$；
$\frac{3}{7} ÷ \frac{3}{7} = \frac{3}{7} × \frac{7}{3} = 1$；
$10 ÷ \frac{1}{5} = 10 × 5 = 50$；
$\frac{1}{4} ÷ \frac{1}{2} = \frac{1}{4} × 2 = \frac{1}{2}$。
