Va rog multtt am nevoie de ajutor urgent!!! Dau coroana​

Answer 1

fractii zecimale:

2,3=23/10

3,2=32/10

2,466=2466/1000

5,77=577/100

9,5=95/10

23,21=2321/100

7,12=712/100

5,8=58/10

56,7=567/10

1,4=14/10

fractii periodice simple:

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

0,(66)=66/99

4,(890)=4890-4/999=4886/999

0,(76)=76/99

4,(8)=48-4/9=44/9

10,(10)=1010-10/99=1000/99

7,(9)=79-7/9=72/9

0,(691)=691/999

3,(3)=33-3/9=30/9

5,(12)=512-5/99=507/99

8,(90)=890-8/99=882/99

fractii periodice mixte:

0,1(1)=11-1/90=10/90

2,0(4)=204-20/90=184/90

1,11(6)=1116-111/900=1005/900

9,3(93)=9393-93/990=9300/990

-> si aici faci la fel cu toate (periodice mixte)
