Пошаговое объяснение:

1

1) -5. 3/4 * 8 = -23/4 * 8 = -23/1 * 2 = -46/1 = -46

2) -2. 1/3 * (-1. 3/14) = -7/3 * (-17/14) =

-1/3 * (-17/2) = 17/6 = 2. 5/6

3) 1. 37/48 * (-2. 2/15) = 85/48 * (-32/15) = 17/3 * (-2/3) = -34/9 = -3. 7/9

4) -46 + 2. 5/6 - (-3. 7/9) =

-46 + 2. 5/6 + 3. 7/9 =

-46 + 2. 30/36 + 3. 28/36 =

-46 + 5. 58/36 = -46 + 6. 22/36 =

-45. 36/36 + 6. 22/36 = -39. 14/36 =

-39. 7/18

2.

1) -4,5 * 1. 2/3 = -4. 5/10 * 1. 2/3 = -45/10 * 5/3 = -15/2 * 1/1 = -15/2 = -7,5

2) 6,75 + (-7,5) = 6,75 - 7,5 = -0,75

3) -0,75 * (-1. 1/3)² = -75/1 00 * (-4/3)² = -3/4 * 16/9 = -1/1 * 4/3 = -4/3 = -1. 1/3
