Answer 1

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

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

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

0,(6) = 6/9 = 2/3

2,(36) = 236 - 2/99 = 234/99 = 26/11

5,(135) = 5135 - 5/999 = 5130/999 = 570/111 = 190/37

1,1(6) = 116 - 11/90 = 105/90 = 35/30 = 7/6

2,708(3) = 27083 - 2708/9000 = 24375/9000 = 8125/3000 = 1625/600 = 325/140 = 65/24

1,25(72) = 12572 - 125/9900 = 12447/9900 = 1383/1100

Answer 2

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

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

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

0,(6)=6/9:3=2/3

2,(36)=(236-2)/99=234/99 simplificam cu 3=78/33:3=26/11

5,(135)=(5135-5)/999=5130/999:3=1710/333:3=570/111

1,1(6)=(116-11) /90=105/90:3=35/30:5=7/6

2,708(3)=(27083-2708)/9000=24375/9000:5=4875/1800:5=975/360:5=195/72:3=65/24

1,25(72)=(12572-125)/9900=12447/9900:9=1383/1100
Sper ca e bine
