Решите уравнение х : 3/4 = 12 1/6 - 9 5/12. 15

Х : 3/4 = 12 1/6 - 9 5/12; Х:3/4=11 7/6-9 5/12; Х:3/4=2 14/12-5/12; Х=2 9/12*3/4; Х=2 3/4*3/4; Х=11/4*3/4; Х=33/16;х=2 1/16; Проверка: 33/16*4/3=2 3/4; 11/4=2 3/4; 2 3/4=2 3/4

Х : 3/4 = 12. 1/6 - 9. 5/12
х : 3/4 = 12. 2/12 - 9. 5/12
х : 3/4 = 11. 14/12 - 9. 5/12
х : 3/4 = 2. 3/4
х = 2. 3/4 * 3/4
х = 33/16
х = 2. 1/16
