2)(3/4+1/3):(7/12-1/24) с решением помогите пожалуйста надо очень быстро отдаю все балы

Answer 1

Пошаговое объяснение:

№1

1) 3/4 * 8/9 = 1/1 * 2/3 = 2/3

2) 2/27 : 4/9 = 2/27 * 9/4 = 1/3 * 1/2 = 1/6

3) 2/3 - 1/6 = 4/6 - 1/6 = 3/6 = 1/2

4) 1/2 + 1 1/2 = 1 2/2 = 2

№2

1) 3/4 + 1/3 = 9/12 + 4/12 = 13/12 = 1 1/12

2) 7/12 - 1/24 = 14/24 - 1/24 = 13/24

3) 1 1/12 : 13/24 = 13/12 * 24/13 = 1/1 * 2/1 = 2/1 = 2

Answer 2

Ответ:

Пошаговое объяснение:

1) 3/4 * 8/9 - 2/27 : 4/9 + 1 1/2 = 2

1) 3/4 * 8/9 = 1/1 * 2/3 = 2/3

2) 2/27 : 4/9 = 2/27 * 9/4 = 1/6

3) 2/3 - 1/6 = 4/6 - 1/6 = 3/6 = 1/2

4) 1/2 + 1 1/2 = 1 2/2 = 2

2) (3/4 + 1/3) : (7/12 - 1/24) = 2

1) 3/4 + 1/3 = 9/12 + 4/12 = 13/12 = 1 1/12

2) 7/12 - 1/24 = 14/24 - 1/24 = 13/24

3) 1 1/12 : 13/24 = 13/12 : 13/ 24 =  13/12 * 24/13 = 2
