$\frac{8}{5} ÷ 4 = $ $\frac{2}{5} ÷ 2 = $ $\frac{5}{8} ÷ 5 = $ $\frac{15}{16} ÷ 3 = $
$\frac{1}{3} ÷ 3 = $ $\frac{9}{14} ÷ 3 = $ $\frac{3}{8} ÷ 2 = $ $\frac{8}{9} ÷ 2 = $
$\frac{11}{12} ÷ 11 = $ $\frac{7}{9} ÷ 8 = $ $\frac{9}{13} ÷ 6 = $ $\frac{2}{3} ÷ 6 = $
$\frac{2}{3} ÷ 4 = $ $\frac{6}{5} ÷ 12 = $ $\frac{10}{9} ÷ 4 = $ $\frac{18}{5} ÷ 9 = $
$\frac{8}{7} ÷ 4 = $ $\frac{10}{3} ÷ 2 = $ $\frac{5}{11} ÷ 5 = $ $\frac{9}{4} ÷ 3 = $
$\frac{18}{13} ÷ 6 = $ $\frac{15}{17} ÷ 5 = $ $\frac{14}{9} ÷ 7 = $ $\frac{12}{11} ÷ 3 = $

1. 列竖式计算。
$10.7 × 0.2 = $ $1.8 × 6.3 = $ $16.74 ÷ 3.1 = $

答案： 1. 2.14 11.34 5.4

2. 脱式计算,能简算的要简算。
$\frac{5}{9} × (\frac{9}{5} + 18)$ $\frac{2}{7} × \frac{5}{3} × \frac{21}{10} + 2$ $7 × 1.3 + 7 × \frac{7}{10}$

答案： 2. 11 3 14
