Answer 1

Ответ:

Пошаговое объяснение:

А)

11. 11/48 - õ = 7. 5/16

õ = 11. 11/48 - 7. 5/16

õ = 11. 11/48 - 7. 15/48

õ = 10. 59/48 - 7. 15/48

õ = 3. 44/48

õ = 3. 11/12

Б)

õ - 2/9 = 1/6 * 1/3

õ - 2/9 = 1/18

õ = 1/18 + 2/9

õ = 1/18 + 4/18

õ = 5/18

B)

õ + 5/19 = 6. 11/38

õ = 6. 11/38 - 5/19

õ = 6. 11/38 - 10/38

õ = 6. 1/38
