oblicz sprytnie 2 i 2/3 + 2 i 4/5 + 1/3 = 7/9 + 1 i 3/4 + 1/4 = 2 i 5/7 + 7 i 2/5 + 2 i 2/7 + 3 i 3/5 = 2 i 3/4 + 1 i 1/6 + 4 i 5/6 + 1 i 2/4 =

2 2/3 + 1/3 + 2 4/5 = 3 + 2 4/5 = 5 4/5 7/9 + 1 3/4 + 1/4 = 7/9 + 2 = 2 7/9 2 5/7 + 2 2/7 + 7 2/5 + 3 3/5 = 5 + 11 = 16 2 3/4 + 1 2/4 + 1 1/6 + 1 5/6 = 4 1/4 + 3 = 7 1/4 Liczę na naj ;)
