1,(3) = 1 + 0.3 + 0.03 + 0.003 + ... = 1 + 0.3/(1-0.1) = 1 + 0.3/0.9 = 1 + 1/3 = 4/3
17(4) = 17 + 0.4 = 17 + 2/5 = 87/5
6,(2) = 6 + 0.2 + 0.02 + 0.002 + ... = 6 + 0.2/(1-0.1) = 6 + 0.2/0.9 = 6 + 2/9 = 56/9
-5,(19) = -5 - 0.19 = -5 - 19/100 = -519/100
7,(13) = 7 + 0.13 = 7 + 13/100 = 713/100
Итак, 1,(3) = 4/3, 17(4) = 87/5, 6,(2) = 56/9, -5,(19) = -519/100, 7,(13) = 713/100.
