Transformati in fractii ireductibile fractiile zecimale:0,6=;1,4=;2,05=;4,75=;0,05=;1,625=;0,375=;1,2525=;0,(5)=;1,(23)=;72,(3)=;3,(402)=;309,(08)=;2,7(3)=;3,9(14)=;5,20(4)=;0,00(18)=;7,1(105)=;0,4(69)=

Answer 1

0,6=6/9=2/3 se simpl cu 3
1,4=14/10=7/5 se simpl cu 2
2,05=205/100=41/20 se simpl cu 5
4,75=475/100=19/4 -se simplifica cu 25
0,05=5/100=1/20 se simpl cu 5
1,625=1625/1000=13/8 se simpl cu 5 de 3 ori
0,375=375/1000=3/8 cu 5 de 3 ori
1,2525=12525/10000=501/400
0,(5)=5/9
1.(23)=123-1/99=122/99
72,(3)=723-2/9=721/9
3,(402)=3402-3/999=3399/999=1133/333
309,(08)=30908-309/99=30599/99
2,7(3)=273-27/90=246/90=82/30
3,9(14)=3914-39/990=3875/990
5,20(4)=5204/900
0,08(18)=818-8/9900=810/9900=90/1100
7,1(105)=71105-71/9990=71034/9990=23678/3330
0,4(69)=469-4/990=465/990=155/330
