3 si 3/5 = 15/5 + 3/5 = 18/5
4 si 2/5 = 20/5 + 2/5 = 22/5
1 si 1/62 = 62/62 + 1/62 = 63/62
3 si 3/5 + 4 si 2/5 + 1 si 1/62 = 18/5 + 22/5 + 63/62 = 40/5 + 63/62 = 8 + 63/62 = 8*62/62 + 63/62 = 496/62 + 63/62 = 559/62 = (558+1)/62 = 558/62 + 1/62 =
= 9 si 1/62
4 si 2/5 = 20/5 + 2/5 = 22/5
1 si 1/62 = 62/62 + 1/62 = 63/62
3 si 3/5 + 4 si 2/5 + 1 si 1/62 = 18/5 + 22/5 + 63/62 = 40/5 + 63/62 = 8 + 63/62 = 8*62/62 + 63/62 = 496/62 + 63/62 = 559/62 = (558+1)/62 = 558/62 + 1/62 =
= 9 si 1/62
