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