Răspuns:

..a) 2,3(6) =236-23/90=213/90=71/30

.1,2(9)= 129-12/90=117/90=39/30=13/10

3,70(2)= 3702-370/900=3332/900=1666/450=833/225

1,2(417)=12417-12/9990=12405/9990=2481/1998

b,) 0,02(03)=203-2/9900=201/9900=67/3300

10,3(27)=10327-3/990=1032/990

11,47(3)=11473-47/900=11426/900=11142/300

0,0002(1)= 21- 2/90000=19/90000

ex 9

0,(0003)= 3/9999=1/3333

0,0(003)=3/9900=1/3330

0,00(03)=3/9900=1/3300

0,000(3)=3/9000=1/3000
