Answer 1

5/8
7/25
1/12 =0,08(3)
3/40=0,075
11/50=0,22
2/3=0,(6)
7/6=1,1(6)
19/18=1,0(5)
103/11 =9,(36)

1,8=18/10=9/5
3,15=315/100=63/20
3,(3)=(33-3)/9=30/9 =10/3
 -5,45=-545/100=-109/20
0,(135)=135/999=5/37
 1,11(2)=(1112-111)/900=1001/900
0,1(235)=(1235-1)9990=1234/9990=614/4995
5,1(6)=(516-51)/90=465/90=93/18=31/6
1,91(6)=(1916-191)/900=1725/900=69/36=23/12

√441=21
 √941≈30,675725...
√2,25=1,5
 √1,0201 =1,01
√25/49=5/7
 √169/225=13/15
√15129=123
