Срочно!!!!!

Answer 1

7/9 : х = 1/3 + 1/18

7/9 : х = 6/18 + 1/18

7/9 : х = 7/18

х = 7/9 : 7/18

х = 7/9 · 18/7

х = 18/9

х = 2

Проверка:

7/9 : 2 = 1/3 + 1/18

7/9 · 1/2 = 6/18 + 1/18

7/18 = 7/18

Answer 2

7/9:x=1/3+1/18

7/9:x=6/18+1/18

7/9:x=7/18

x=7/9:7/18

x=7/9•18/7(сокращаем, 1/1 2/1)

x=2/1 иначе 2
