Реши уравнения 5/6:3/3= 9

Пропущен х.

Если : 5/6х : 3/3 = 9; то

5/6х = 9 : 3/3;

5/6х = 9 : 1;

5/6х = 9;

х = 9 : 5/6;

х = 9 * 6/5;

х = 54/5;

5/6 * 54/5 : 3/3 = 9;

9 : 1 = 9;

9 = 9.

Если 5/6 : 3/3х = 9, то 

3/3х = 5/6 : 9/1;

х = 5/6 * 1/9;

х = 5/54;

5/6 : 5/54 = 9;

5/6 * 54/5 = 9;

9 = 9.

Если 5/6 : 3/3 = 9х, то

5/6 : 1 = 9х;

5/6 = 9х;

9х = 5/6;

х = 5/6 : 9;

х = 5/6 * 1/9;

х = 5/54;

5/6 : 3/3 = 9 * 5/54;

9 = 9.
