1)
5/16 + x = 9/16 |*16
5 + 16x = 9
16x = 9 - 5
16x = 4
x = 4/16
x = 1/4
x = 0,25
ответ: 0,25
2)
(17/28 - x) - 11/28 = 3/28
17/28 - x = 3/28 + 11/28
17/28 - x = 14/28
x = 17/28 - 14/28
x = 3/28
ответ: 3/28
3)
x/25 - 4/25 = 13/25 |*25
x - 4 = 13
x = 13 + 4
x = 17
ответ: 17

2)
(17/28 - x) - 11/28 = 3/28
17/28 - x = 3/28 + 11/28
17/28 - x = 14/28
x = 17/28 - 14/28
x = 3/28
ответ: 3/28
3)
x/25 - 4/25 = 13/25 |*25
x - 4 = 13
x = 13 + 4
x = 17
ответ: 17
