a) 2 целых 1/2 = 22 +1/2 = 5/2
Разность 22 +1/2 - 2/3 = 5/2 - 2/3 = (53 - 22)/(2*3) = (15 - 4)/6 = 11/6
b) 3 целых 2/3 = 33 + 2/3 = 11/3
Разность 33 + 2/3 - 24/5 = 11/3 - 8/5 = (115 - 83)/(35) = (55 - 24)/15 = 31/15
c) 2 целых 3/4 = 24 + 3/4 = 11/4
Разность 24 + 3/4 - 15/6 = 11/4 - 5/6 = (116 - 54)/(46) = (66 - 20)/24 = 46/24 = 23/12
Итак, разности:
a) 11/6
