$frac{8}{25} times frac{5}{56} = frac{8}{5 times 5} times frac{5}{7 times 8} = frac{1}{35}$
$frac{5}{8} times frac{7}{9} = frac{35}{72}$
$frac{37}{88} times frac{24}{37} = frac{8 times 3}{8 times 11} = frac{3}{11}$
$frac{29}{69} times frac{23}{58 } = frac{29}{23 times 3} times frac{23}{29 times 2} = \ = frac{1}{2 times 3} = frac{1}{6}$
$8 times frac{5}{49} = frac{8 times 5}{49} = frac{40}{49}$
$frac{9}{56} times 72 = frac{9 times 9 times 8}{8 times 7} = \ = frac{81}{7} = 11 frac{4}{7}$
$5 frac{1}{19} times 1 frac{5}{32} = frac{24}{19} times frac{37}{32} = \ = frac{8 times 3}{19} times frac{37}{4 times 8} = frac{3 times 37}{19 times 4} = \ = frac{111}{76} = 1 frac{35}{76}$
$frac{5}{14} times 4 frac{2}{3} = frac{5}{14} times frac{14}{3} = \ = frac{5}{3} = 1 frac{2}{3}$
