Answer 1

$frac{2*5}{3*6} = frac{2*5}{3*3*2} = frac{5}{3*3} = frac{5}{9}$
$frac{2*7}{9*4} = frac{2*7}{9*2*2} = frac{7}{9*2} = frac{7}{18}$
$frac{3*5}{20*2} = frac{3*5}{4*5*2} = frac{3}{4*2} = frac{3}{8}$
$frac{4*3}{9*7} = frac{4*3}{3*3*7} = frac{4}{3*7} = frac{4}{21}$
$frac{10*3}{23*10} = frac{3}{23}$
$frac{10*2}{21*30} = frac{10*2}{21*3*10} = frac{2}{63}$
$frac{4*5}{15*16}= frac{4*5}{3*5*4*4} = frac{1}{3*4} = frac{1}{12}$
$frac{8*9}{27*16} = frac{8*9}{3*9*2*8} = frac{1}{3*2} = frac{1}{6}$
