ntk1 5/6*1/2=5*1/6*2=5/12.
2/3*2/5=2*2/3*5=4/15.
4/3*5/7=4*5/3*7=20/21.
3/10*3/10=3*3/10*10=9/100.

Darik2020 $\frac{5}{6} * \frac{1}{2} = \frac{5}{12}$
$\frac{2}{3} * \frac{2}{5} = \frac{4}{15}$
$\frac{4}{3} * \frac{5}{7} = \frac{20}{21}$
$\frac{3}{10} + \frac{3}{10} = \frac{9}{100}$
$\frac{3}{4} + \frac{3}{7} = \frac{9}{28}$
$\frac{5}{7} + \frac{9}{1} = \frac{45}{7} =6 \frac{3}{7}$
