помогите срочно нужно пожалуйста ​

Answer 1

Ответ:

1. 1/3

2. 2 7/12

3. 2 1/8

Пошаговое объяснение:

1. (1 1/2)² * 4 * 1/27 = (3/2)² * 4 * 1/27 = 9/4 * 4 * 1/27 = 9/27 = 1/3

2. (4 3/10 - 3 3/5 * 5/15) * 5/6 = (4 3/10 - 18/5*5/15) * 5/6 =

(4 3/10 - 18/15) * 5/6 = (43/10 - 18/15) * 5/6 = (129/30 - 36/30) * 5/6 =

93/30 * 5/6 = 31/10 * 5/6 = 31/12 = 2 7/12

3. 1 4/5 * (5/24 + 5/16) * (3/5 + 1 2/3) = 9/5 * (10/48 + 15/48) * (3/5 + 5/3) =

9/5 * 25/48 * (9/15 + 25/15) = 45/48 * 34/15 = 2 1/8
