Answer 1

Răspuns:

Explicație pas cu pas:

1,(3)=12/9

2,(12)=210/9

5,(5)=50/9

7,(4)=67/9

0,(13)=13/9

2,(43)=241/9

2,1(3)=192/90

3,2(5)=293/90

4,2(5)=383/90

2,1(8)=197/90

4,2(4)=382/90

Answer 2

Salut!

1,(3)=(13-1)/9=12/9=4/3

2,(12)=(212-2)/99=210/99=70/33

5,(5)=(55-5)/9=50/9

7,(4)=(74-7)/9=67/9

0,(13)=13/99

2,(43)=(243-2)/99=241/99

2,1(3)=(213-21)/90=192/90=96/45

3,2(5)=(325-32)/90=293/90

4,2(5)=(425-42)/90=383/90

2,1(8)=(218-21)/90=197/90

4,2(4)=(424-42)/90=382/90=191/45

Succes!
