d) 2,0(3) - 1,0(2)
e) 2,3(7) - 1,2 (3)
f) 1,(15) + 0,(23)
g) 1,21 ( 3) - 0,12(3)
h) 4,(92) - 1,(75)

Answer 1

a. 2/9+3/9=5/9
b. (25-2)/9+(15-1)/9=23/9+14/9=37/9
c.(115-1)/99+5/99=114/99+5/99=119/99
d.(203-20)/90-(102-10)/90=183/90-92/90=91/90
e. (237-23)/90-(123-12)/90=214/90-111/90=103/90
f. (115-1)/99+23/99=114/99+23/99=137/99
g. (1213-121)/900-(123-12)/900=1092/900-111/900=981/900 impartim la 9=109/100
h. (492-4)/99-(175-1)/99=484/99-174/99=310/99

Answer 2

2\9+3/9=5/9
b)25/9+15/9=40/9
c)115/9+5/9=120/9
d)203/9-102/9=101/9
e)237/9-123/9=114/9
f)115/9+23/9=138/9
g)1213/9-123/9=1090/9
h)492/9-175/9=320/9
