Пошаговое объяснение:
х - 5/18 = 1 17/64 * 16/27
х - 5/18 = 81/64 * 16/27
х - 5/18 = 3/4
х = 3/4 + 5/18
х = 27/36 + 10/36
х = 37/36
х = 1 1/36
1 1/36.
(x-5/18)÷16/27=1 17/64
x - 5/18 = 16/27•1 17/64
x - 5/18 = 16/27•81/64
x - 5/18 = (16•81)/(27•64)
x - 5/18 = (1•3)/(1•4)
x - 5/18 = 3/4
х = 5/18 + 3/4
х = 10/36 + 27/36
Проверка:
(1 1/36 - 5/18)÷16/27=1 17/64
(37/36 - 10/36) : 16/27=1 17/64
27/36 • 27/16 = 1 17/64
(27•27)/(36•16) = 1 17/64
(3•27)/(4•16) = 1 17/64
81/64 = 1 17/64
1 17/64 = 1 17/64 - верно
