Answer 1

1)  2,4= 24/10
    0,13= 13/100
    0,145=145/1000
2) 1,(3)= 13-1/9=12/9
    4,(6)=46-4/9=42/9
    15,(2)=152-15/9=137/9
     6,(23)=623-6/99=617/99
     7,(63)=763-7/99=756/99
     0,(18)=18/99
    0,(108)=108/999
    5,(036)=5036-5/999=5031/999
    1,2(3)=123-12/90=111/90
    6,0(12)=6012-60/990=5952/990
    0,01(4)=14-1/900=13/900
    5,00(8)=5008-500/900=4508/900
    16,40(81)=160481-1640/9900=162441/9900
     0,3(102)=3102-3/9990=3090/9990
3) 11/3=3,(6)
     10/7=1,428
     1/6=0,1(6)
    12/11=1,(09)
     1/2=0,5
     7/4=1,75
     7/22=0,3(18)
    5/7=0,714
    3/14=0,214
    2/5=0,4
    1/8=0,125
   13/20=0,65
