答案： 解析：本题考查分数的四则运算，包括分数的乘法、除法、加法和减法。
答案：
$\frac{3}{5} × \frac{1}{3} = \frac{1}{5}$
$\frac{1}{2} + \frac{3}{4} = \frac{5}{4}$
$\frac{1}{7} ÷ \frac{1}{2} = \frac{2}{7}$
$\frac{3}{4} × \frac{1}{3} = \frac{1}{4}$
$24 ÷ \frac{2}{3} = 36$
$14 × \frac{5}{7} = 10$
$\frac{3}{8} × \frac{4}{5} = \frac{3}{10}$
$1 ÷ \frac{5}{7} = \frac{7}{5}$
$\frac{5}{8} + \frac{4}{8} = \frac{9}{8}$
$\frac{8}{9} ÷ 4 = \frac{2}{9}$
$\frac{9}{5} × \frac{2}{3} = \frac{6}{5}$
$\frac{7}{8} - \frac{3}{4} = \frac{1}{8}$
$\frac{8}{11} ÷ 8 = \frac{1}{11}$
$\frac{2}{3} ÷ \frac{3}{2} = \frac{4}{9}$
$\frac{1}{2} ÷ 2 = \frac{1}{4}$
$\frac{1}{3} × 27 = 9$
$\frac{1}{4} + \frac{1}{3} = \frac{7}{12}$
$\frac{4}{5} × 5 = 4$
$\frac{3}{5} × 15 = 9$
$\frac{4}{5} - \frac{3}{10} = \frac{1}{2}$
