Вычислите 4 5/12 + 1 1/12 : ( 6 5/8 - 3 11/12 ) * 4 1/6

4 5/12 + 11/12 / (6 5/8 - 3 11/12) * 4 1/6 = 53/12 + 11/12 /(53/8 - 47/12) * 25/6=
53/12 + 11/12/ (159/24 - 94/24) * 25/6 = 53/12 + 11/12 / 65/24 * 25/6 = 53/12 + 22/65 * 25/6 = 53/12 + 55/39 = 689/156 + 220/156 = 909/156 = 303 / 52 =
5 43/52
