Salutare!
(a)
19/3 = (18 + 1)/3 = (3 × 6 + 1)/3 = (3 × 6)/3 + 1/3 = 6 intregi 1/3
19 : 3 = 6, rest 1
(b)
23/7 = (21 + 2)/7 = (3×7 + 2)/7 = (3×7)/7 + 2/7 = 3 + 2/7 = 3 intregi 2/7
23 : 7 = 3, rest 2
(c)
26/9 = (18+8)/9 = (2×9+8)/9 = (2×9)/9 + 8/9 = 2 + 8/9 = 2 intregi 8/9
26 : 9 = 2, rest 8
(d)
43/20 = (40+3)/20 = (2×20+3)/20 = (2×20)/20 + 3/20 =
2 + 3/20 = 2 intregi 3/20
43 : 20 = 2, rest 3
