$2 + 2\% =$ $0.75×10\% =$ $32×12.5\% =$
$16×5\% =$ $2.4×0.5\% =$ $80×1.25\% =$
$40÷50\% =$ $4.2÷70\% =$ $16.8÷4\% =$

答案：

$\frac{1}{9} - \frac{1}{9}×\frac{1}{9} =$ $\frac{3}{7}×\frac{2}{5}×5×7 =$ $\frac{3}{4}×\frac{5}{6}÷\frac{5}{6}×\frac{3}{4} =$
$0.5÷\frac{3}{4}÷\frac{1}{2} =$ $(\frac{1}{4} - \frac{1}{5})×20 =$ $(6.25 - 6\frac{1}{4})×3.8 =$
$\frac{4}{5}×4 + 4×\frac{1}{4} =$ $5 - 1.4 - 1.6 =$ $\frac{1}{8}×1.25×8 =$
$6.4 + 9.6 - 12 =$ $(1 - \frac{7}{8})×16 =$ $(\frac{2}{5} - \frac{1}{6})×30 =$
$\frac{2}{3}×\frac{1}{5}÷2×15 =$ $\frac{1}{3}×\frac{1}{3}÷\frac{1}{9}×9 =$ $5÷\frac{1}{5} + \frac{1}{5}÷5×\frac{1}{5} =$
$12×(\frac{1}{3} - \frac{1}{4}) =$ $\frac{3}{8} - \frac{3}{8}÷3 =$ $1.4×\frac{5}{7}÷1\frac{2}{5} =$
$(\frac{5}{8} + 0.375)÷\frac{5}{8} =$ $\frac{5}{9}×9÷\frac{5}{9}×9 =$ $1 + 1÷3 + \frac{2}{3} =$
