Answer 2

Răspuns: 1

Explicație pas cu pas:

[0,(3) + 1,(3) : 1 i 7/9] : (1 + 1/12) =

0,(3) = 3/9

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

1 intreg 7/9 = (1x9+7)/9 = 16/9

[ 3/9 + 12/9 : 16/9 ] : (12+1)/12 =

[3/9 + 12/9 x 9/16] : 13/12 =

[3/9 + 12/16] x 12/13

[3/9 + 3/4] x 12/13 =

(3x4+3x9)/36  x  12/13 =

(12+27)/36  x 12/13 =

39/36  x 12/13 =

13/12  x 12/13 =
