Давайте посчитаем:
(1 5/54 - 11/36) = 59/54 - 11/36 = (592 - 113) / (54*2) = (118 - 33) / 108 = 85 / 108 = 5/6
3 3/5 = (35 + 3) / 5 = 18/52 2/7 = (27 + 2) / 7 = 16/71 2/7 = (17 + 2) / 7 = 9/71 5/9 = (19 + 5) / 9 = 14/9 = 1 5/9
Теперь подставим найденные значения:
(5/6) (18/5) (16/7) - (9/7) (14/9) = (5/6) (18/5) (16/7) - (9/7) (14/9)= (30/7) (16/7) - (9/7) (14/9) = 480/49 - 126/63 = (48063 - 12649) / (49*63)= (30240 - 6174) / 3087 = 24066 / 3087 = 36/7 = 5 1/7
