Odpowiedź:
6/7 + ... = 1 i 3/7
1 i 3/7 - 6/7 = 10/7 - 6/7 = 4/7
spr 6/7 + 4/7 = 10/7 = 1 i 3/7
1 i 3/4 + .... = 2 i 1/4
2 i 1/4 - 1 i 3/4 = 1 i 5/4 - 1 i 3/4 = 2/4
spr 1 i 3/4 + 2/4 = 1 i 5/4 = 2 i 1/4
17 i 3/5 + .... = 19 i 2/5
19 i 2/5 - 17 i 3/5 = 18 i 7/5 - 17 i 3/5 = 1 i 4/5
spr 17 i 3/5 + 1 i 4/5 = 18 i 7/5 = 19 i 2/5
..... + 2 i 3/8 = 7 i 1/8
7 i 1/8 - 2 i 3/8 = 6 i 9/8 - 2 i 3/8 = 4 i 6/8
spr 4 i 6/8 + 2 i 3/8 = 6 i 9/8 = 7 i 1/8
