Question

Scrieti 15 transformari care nu au numitorii 10,100,1000 etc.(Fractii zecimale)

Answer 1

 0,3 = 3/10
5,6 = 56/10= 28/5
0,(5) = 5/9
0,(3) =3/9
3,(5) = 35/9
3,(85) = 385/99
0,(056) = 56/999
0,3(44) =  (344 - 3)/990 = 341/990
0,(1) = 1/9
1,(23) = (123 – 1)/99
12,(345) = (12345 -12)/999=12333/999
0,1(2) = (12-1)/90=11/90
1,23(45) = (12345 – 123)/9900=123222/9900
12,34(567) = (1234567 – 1234)/99900
3,(5)=3si 5/9=32/9

Answer 2

12,(7)=127-12/9
32,(54)=3254-32/99
123,(8)=1238-123/9
345,(89)=34589-345/99
0,(989)=989/999
124,(789)=124789-124/999
345,(90)=34590-345/99
157,(2)=1572-157/9
284,(4)=2844-284/9
581,(91)=58191-581/99
456,(12)=45612-456/99
297,(7)=2977-297/9
13,(23)=1323-13/99
14,(78)=1478-14/99
51,(21)=5121-51/98
