1. 直接写出得数。（6分）
$\frac {2}{9} × \frac {9}{8} =$ $\frac {3}{4} × \frac {4}{7} =$ $\frac {7}{18} × \frac {9}{14} =$
$\frac {10}{21} × \frac {7}{5} =$ $\frac {15}{39} × \frac {13}{25} =$ $\frac {17}{45} × \frac {25}{34} =$
$\frac {4}{13} × \frac {39}{16} =$ $\frac {63}{64} × \frac {36}{42} =$ $\frac {2}{9} × \frac {1}{8} =$
$\frac {15}{16} × \frac {20}{21} × \frac {7}{5} =$ $\frac {9}{10} × \frac {2}{3} × \frac {5}{6} =$ $\frac {5}{4} × \frac {1}{8} × 16 =$
