Пошаговое объяснение:
(95 + 305) : 5 = 400 : 5 = 80
241 + 123 + 59 + 27 = (241 + 59) + (123 + 27) = 300 + 150 = 450
(330 + 30 + 90) : 30 = 330 : 30 + 30 : 30 + 90 : 30 = 11 + 1 + 3 = 15
(123 + 77) * 2 = 200 * 2 = 400
448 + 222 + 60 = (448 + 222) + 60 = 670 + 60 = 730
(12 + 18 + 20) * 6 = ((12 + 18) + 20) * 6 = (30 + 20) * 6 = 50 * 6 = 300
