Answer 1

Ответ:   1.

Пошаговое объяснение:

2 3/5 : 2 2/5 - 1 1/12 + 1 40/72 * (5 5/7-5 1/14) = 1.

1)  2 3/5 : 2 2/5 = 13/5 : 12/5 = 13/5 * 5/12 = 13/12;

2)  5 5/7 - 5 1/14 = 5 10/14 - 5 1/14 = 9/14;

3)  1 40/72 * 9/14 = 112/72 * 9/14 = 1;

4)  13/12 - 1 1/12 = 13/12 - 13/12 = 0;

5)  0+1 = 1.

Answer 2

Ответ:

Пошаговое объяснение:

1) 2. 3/5 : 2. 2/5 = 13/5 : 12/5 = 13/5 * 5/12 = 13/12 = 1. 1/12

2) 5. 5/7 - 5. 1/14 = 5. 10/14 - 5. 1/14 = 9/14

3) 1. 40/72 * 9/14 = 112/72 * 9/14 = 8/8 * 1/1 = 8/8 = 1

4) 1. 1/12 - 1. 1/12 = 0

5) 0 + 1 = 1
