2/х = 27/1082/х = 1/42 =х/48 = x
Ответ: x = 8
х / (2/3) = 3 3/8 / 3х 3/2 = 27/83х/2 = 27/83х = 27/8 23х = 54/8х = 18/8х = 2 1/4
Ответ: х = 2 1/4
2/х = 27/108
2/х = 1/4
2 =х/4
8 = x
Ответ: x = 8
Решим уравнение х:2/3 = 3 3/8 : 3:х / (2/3) = 3 3/8 / 3
х 3/2 = 27/8
3х/2 = 27/8
3х = 27/8 2
3х = 54/8
х = 18/8
х = 2 1/4
Ответ: х = 2 1/4
