Explicație pas cu pas:

10.

1,(2) = (12 - 1)/9 = 11/9

11/9 + 1 = 11/9 + 9/9 = 20/9

11/9 - 1 = 11/9 - 9/9 = 2/9

(20/9)/(2/9) = 20/9*9/2 = 20/2 = 10

__________

1,3(2) = (132 - 13)/90 = 119/90

119/90 + 1 = 119/90 + 90/90 = 209/90

119/90 - 1 = 119/90 - 90/90 = 29/90

(209/90)/(29/90) = 209/90*90/29 = 209/29

__________

(10 + 209/29 + 226/29) : 25 = (10 + 435/29) : 25 = (10 + 15) : 25 = 25 : 25

= 1
