Question

0,(15):1,(3)
0,1(1):1,2(3)
1,0(2):1,02​

Answer 1

Răspuns:

Explicație pas cu pas:

0,(15):1,(3)

0,(15) = 15/99 = 5/33

1,(3) = (13 - 1)/9 = 12/9 = 4/3

5/33 : 4/3 = 5/33*3/4 = 5/44

________________

0,1(1):1,2(3)

0,1(1) = (11 - 1)/90 = 10/90 = 1/9

1,2(3) = (123 - 12)/90 = 111/90

1/9 : 111/90 = 1/9 * 90/111 = 10/111

-------------------------------

1,0(2):1,02​

1,0(2) = (102 - 10)/90 = 92/90 = 46/45

1,02 = 102/100 = 51/50

46/45 : 51/50 = 46/45*50/51 = 460/459
