Ответ:
А) 6/5; Б) 4/9; В) 133/360; Г) 193/660
Пошаговое объяснение:
А) 2/5 + 1/2 + 3/10 = (4+5+3)/10 = 12/10 = 6/5
Б) 5/18 - 1/6 + 1/3 = (5-3+6)/18 = 8/18 = 4/9
В) 7/24 - 7/60 + 7/36 = 7*(1/24 - 1/60 + 1/36) = 7*(15-6+10)/360 = 7*19/360 = 133/360
Г) 8/33 + 7/44 - 6/55 = 1/11*(8/3 + 7/4 - 6/5) = 1/11*(160+105-72)/60 = 193/660
