2,(9) = 2 i 9/9 = 3
a) 3 + 2,(9) = 3 + 3 = 6
0,(9) = 9/9 = 1
b) 4 - 0,(9) = 4 - 1 = 3
c) 5 +2,(9) = 5 + 3 = 8
d) 1 + 0,(9) = 1 + 1 = 2
e) 0,(3) +1/7 = 3/9 + 1/7 = 1/3 + 1/7 = 7/21 + 3/21 = 10/21
f) 0,(4) + 0,(5) = 4/9 + 5/9 = 9/9 = 1
g) 0,1(2) + 0,2(1) = 11/90 + 19/90 = 30/90 = 1/3
h) 1,(09) + 0,(90) 1 i 9/99 + 90/99 = 1 i 99/99 = 2
