c) -16/10 : 56/15 + 17/14 = -16/10 * 15/56 + 17/14 = -12/28 + 17/14 = -12/28 + 34/28 = 22/28 = 11/14
d) (3/10 + 4/5) : (91/15 - 2/3) = (11/10) : (91/15 – 10/15) = (11/10) * (15/81) = (11/10) * (5/27) = 11/54
e) Nawiasy dodane aby kolejność działań była bardziej przejrzysta
[(16/10 - 2/3 )/ (16/10) ]* 2/3 = (48/30 – 20/30)*(10/16)*(2/3)=(28/30)*(10/16)*(2/3)=7/18
f) (48/10 / 16/15 )- (9/4 / 54/10 )= 48/10 * 15/16 - 9/4 * 10/54 = 9/2 - 5/12 = 54/12 - 5/12 = 49/12
