Ответ:
а) 48
б) 5
в) 11/15
г) 4/5
д) 5/7
е) 1
Пошаговое объяснение:
а) 48 * (5/17 + 12/17) = 48 * 17/17 = 48 * 1 = 48
б) 55 * (7/11 - 6/11) =
55 * 1/11 = 55/11 = 5
в) 11/13 * (11/15 + 2/15) = 11/13 * 13/15 = 11/15
г) 12/19 * (23/15 - 4/15) = 12/19 * 19/15 = 12/15 = 4/5
д) 5/14 * (22/21 + 20/21) = 5/14 * 42/21 = 5/1 * 3/21 = 15/21 = 5/7
е) 1/2 * (47/11 - 25/11) = 1/2 * 22/11 = 22/22 = 1
