Răspuns:

Explicație pas cu pas:

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

2/3 + 4/3 = 6/3 = 2

____________

0,1(3) = (13 - 1)/90 = 12/90

0,9(3) = (93 - 9)/90 = 84/90

12/90 + 84/90 = 96/90 = 16/15

____________

0,(75) = 75/99 = 25/33

25/33 + 8/33 = 33/33 = 1

____________

0,(63) = 63/99 = 21/33

12/33 + 21/33 = 33/33 = 1
