Answer 1

1.
a)13/75=0,17(3)
b)7/8=0,875
c)3 intregi 12/25 =3+0,48=3,48
   -2intregi 17/55 =-[2+0,3(09)]=-2,3(09)

2.
a) -0,756 =-756/1000=-189/250
b) 0,(756)=756/999=84/111=28/37
c) 0,7(56)=(756-7)/990=749/990
d) -3,75(6)=-(3756-375)/900=-3381/900=-1127/300
2,63636363=2,(63)=(263-2)/99=261/99=29/11
