一、计算下面各题，能用简便算法的就用简便算法。
$\frac{23}{25} × 0.25 + 0.25 × \frac{2}{25}$
$( \frac{5}{6} - \frac{3}{7} + \frac{9}{14} ) × 42$
$\frac{3}{4} - \frac{1}{6} × \frac{9}{10} + \frac{5}{6}$
$\frac{12}{5} × ( \frac{1}{6} + \frac{1}{4} ) + \frac{1}{5}$
$5 ÷ \frac{9}{10} ÷ ( \frac{5}{27} - \frac{1}{9} )$
$\frac{7}{10} ÷ 8 × \frac{5}{14} - \frac{1}{32}$
$( 1 - \frac{1}{4} × \frac{8}{9} ) ÷ \frac{7}{9}$
$\frac{3}{4} ÷ ( \frac{13}{24} - \frac{5}{18} × \frac{7}{10} )$
$\frac{3}{5} × 8.1 + 1.9 ÷ \frac{5}{3}$
$( 0.25 - 0.125 ) × ( 60 - 28 )$
$[ 1 - ( \frac{2}{3} + \frac{1}{5} ) × \frac{1}{13} ] ÷ \frac{7}{10}$
$17 × [ \frac{3}{8} + ( \frac{5}{4} - \frac{5}{6} ) ]$
$\frac{9}{10} ÷ [ 0.5 × ( \frac{6}{5} - 0.3 ) ]$
