Ответ:

5 3/9×9/16=48/9×9/16=48/16=3/1=3

13/20×3 1/13=13/20×40/13=40/20=2/1=2

17/6×12/34=2/2=1

Answer 2

$\displaystyle\\5\frac{3}{9}*\frac{9}{16} = \frac{48}{9}*\frac{9}{16}=\frac{3}{1}*\frac{1}{1}=\frac{3}{1}=3\\\\\\\frac{13}{20}*3\frac{1}{13}=\frac{13}{20}*\frac{40}{13}=\frac{1}{1}*\frac{2}{1}=\frac{2}{1}=2\\\\\\\frac{17}{6}*\frac{12}{34}=\frac{1}{1}*\frac{2}{2}= \frac{2}{2}=1$
