Вычислить 9- 2 целых 1/2 разделить на 3 целых 3/4 - (2 целых 1/2 - 1 целая 1/3 )*12

9 - 2 1/2 : 3 3/4 - (2 1/2 - 1 1/3 ) * 12 = 9 - 5/2 : 15/4 - (5/2 - 4/3 ) * 12 = 9 - 5/2 * 4/15 - (15/6 - 8/6 ) * 12 = 9 - 4/2 * 5/15 - (15 - 8)/6 * 12 = 9 - 2 * 1/3 - 7/6 * 12 = 9 - 2/3 - 7 * 12/6 = 9 - 2/3 - 7 * 2 = 9 - 2/3 - 14 = 9 - 14 - 2/3 = (9 - 14) - 2/3 = -(-9 + 14) - 2/3 = -(14 - 9) - 2/3 = -5 - 2/3 = -15/3 - 2/3 = (-15 - 2)/3 = -(15 + 2)/3 = -17/3 = -5 2/3Ответ: -5 2/3
