$2) \frac{5}{2} \times \frac{14}{5} = 7$
$3) \frac{16}{7} \times \frac{9}{8} = \frac{18}{7} = 2 \frac{4}{7}$
$4) \frac{8}{5} \times \frac{15}{2} = 12$
$5) \frac{15}{7} \times \frac{32}{15} = \frac{32}{7} = 4 \frac{4}{7}$
$6) \frac{20}{9} \times \frac{99}{40} = \frac{11}{2} = 5 \frac{1}{2} = 5.5$
$7) \frac{21}{10} \times \frac{15}{7} = \frac{9}{2} = 4 \frac{1}{2} = 4.5$
