a) sprawdz czy takie sa dane, bo z tego co obliczam to srednio cos wychodzi..
b)2i99/128
12 i 5/9*10 i 5/6 + (2 i 7/12 + 3 i 58)=113/9 * 65/6 + (2 i 59/96 + 3 i 60/96)=7345/54 + 5 i 116/96 = 136 i 1/54 + 6 i 20/96=142 i 49/216
3 i 1/8 * 1 i 1/5 - 3 i 1/8 : 3 i 1/5 = 25/8 * 6/5 - 25/8 * 5/16 = 5/8 * 6/5 - 25/8 * 5/16 = 30/8 - 125/128 = 480/128 - 125/128 = 355/128 = 2 i 99/128
