$\frac{1}{4} * \frac{2}{3} = \frac{1*2}{4*3} = \frac{1*1}{2*3} = \frac{1}{6} \\ \\ 
 \frac{4}{9} * \frac{1}{2} = \frac{4*1}{9*2} = \frac{2*1}{9*1} = \frac{2}{9} \\ \\$
$\frac{2}{3} * \frac{3}{8} = \frac{2*3}{3*8} = \frac{1*1}{1*4} = \frac{1}{4} \\ \\ 
 \frac{5}{12} * \frac{8}{9} = \frac{5*8}{12*9} = \frac{5*2}{3*9} = \frac{10}{18} \\ \\$
$\frac{15}{16} * \frac{8}{25} = \frac{15*8}{16*25} = \frac{3*1}{2*5} = \frac{3}{10} \\ \\ 
 \frac{1}{2} * \frac{2}{3} = \frac{1}{3} \\ \\$
$\frac{3}{4} * \frac{1}{6} = \frac{1*1}{4*2} = \frac{1}{8}$

$\frac{7}{15} * \frac{5}{7} = \frac{1*1}{3*1} = \frac{1}{3}$
