Answer 1

1820=9/10

530=1/6

1612=1 1/3

3020=1 1/2

9/12=3/4

28=1/4

Answer 2

9/10 , 1/6 , 1 целая 4/12 потом 1 целая 1/3 , 1 целая 1/2 , 3/4 , 1/4 

Answer 3

$ttdisplaystyle frac{18}{20}=frac{18:2}{20:2}=frac{9}{10}=0,9\\\frac{5}{30}=frac{5:5}{30:5}=frac{1}{6}\\\frac{16}{12}=frac{16:4}{12:4}=frac{4}{3}=1frac{1}{3}\\\frac{30}{20}=frac{30:10}{20:10}=frac{3}{2}=1frac{1}{2}=1,5\\\frac{9}{12}=frac{9:3}{12:3}=frac{3}{4}=0,75\\\frac{2}{8}=frac{2:2}{8:2}=frac{1}{4}=0,25$
