Answer 1

Ответ:

-25. 2/5

Пошаговое объяснение:

1) -4. 1/4 * 8 = -17/4 * 8 = -17/1 * 2 = -34/1 = -34

2) -2. 2/3 * (-1. 3/5) = -8/3 * (-8/5) = 64/15 = 4. 4/15

3) 1. 29/36 * (-2. 2/5) = 65/36 * (-12/5) = 13/3 * (-1/1) = -13/3 = -4. 1/3

4) -34 + 4. 4/15 = -33. 15/15 + 4. 4/15 = -29. 11/15

5) -29. 11/15 - (-4. 1/3) = -29. 11/15 + 4. 1/3 = -29. 11/15 + 4. 5/15 = -25. 6/15 = -25. 2/5
