Answer 1

Пошаговое объяснение:

1/2*1/5=1/10

2/3*1/4=2/12=1/6

3/5:1=3/5

1/7:2/3=3/14

1:1/5=1/5

5/6*6=5

0:8/9=0

3/8*1/2=3/16

2/3:5/7=14/15

9/10*1=9/10

2:2/3=3

1/9:1/3=1/3

Answer 2

$\frac{2}{5} *2=\frac{4}{5}$

$\frac{1}{2} *\frac{1}{5} =\frac{1}{10}$

$\frac{2}{3} *\frac{1}{4} =\frac{1}{6}$

$\frac{3}{5} :1=\frac{3}{5}$

$\frac{1}{7} :\frac{2}{3} =\frac{1}{7} *\frac{3}{2} =\frac{3}{14}$

$1:\frac{1}{5} =1*\frac{5}{1}=5$

$\frac{5}{6} *6=\frac{5*6}{6}=5$

$0:\frac{8}{9}=0$

$\frac{3}{8} *\frac{1}{2} =\frac{3}{16}$

$\frac{2}{3} :\frac{5}{7} =\frac{2}{3} *\frac{7}{5} =\frac{14}{15}$

$\frac{9}{10} *1=\frac{9}{10}$

$2:\frac{2}{3}= 2*\frac{3}{2}= 3$

$\frac{1}{9} :\frac{1}{3} =\frac{1}{9} *\frac{3}{1} =\frac{1}{3}$
