1. 直接写出得数。
$\frac{8}{11} ÷ 8 =$
$\frac{3}{2} × \frac{2}{3} =$
$\frac{1}{4} + \frac{1}{4} =$
$26 × \frac{12}{13} =$
$\frac{4}{5} - \frac{7}{10} =$
$5 ÷ \frac{5}{7} =$
$\frac{3}{8} ÷ 3 =$
$\frac{1}{2} × \frac{1}{2} =$
$\frac{5}{9} - \frac{1}{3} =$
$\frac{7}{15} × \frac{1}{7} =$
$3 - \frac{9}{5} =$
$\frac{2}{5} ÷ \frac{7}{12} =$
$\frac{7}{8} ÷ \frac{1}{2} =$
$\frac{2}{5} × \frac{7}{12} =$
$0 ÷ 9\frac{1}{10} =$

1.$\frac{1}{11}$

2. 递等式计算。
$\frac{5}{12}÷\frac{1}{4}×\frac{4}{15}$
$\frac{5}{12}÷(\frac{1}{4}×\frac{4}{15})$
$\frac{7}{8}÷\frac{6}{5}+\frac{1}{8}×\frac{5}{6}$
$2.8×(\frac{1}{7}+\frac{3}{28})$
$\frac{11}{12}×7÷\frac{7}{12}$
$99×\frac{99}{100}$

1.$\frac{4}{9}$
2.$\frac{25}{4}$
3.$\frac{5}{6}$
4.$\frac{7}{10}$
5.$11$
6.$98\frac{1}{100}$
