Пошаговое объяснение: Удачи...

8 1/4 • (-3 1/3)•(-2 2/15) +(1-67/69)•23/24=58 3/4

1) 1-67/69=69/69-67/69=2/69

2) 8 1/4 • (-3 1/3)=-33/4*10/3=-27 1/2

3) -27 1/2•(-2 2/15)=55/2*32/15=58 2/3

4) 2/69•23/24=3/36

5) 58 2/3+3/36=2112/36+3/36=58 3/4

Answer 2

Ответ:

58. 25/36

Пошаговое объяснение:

1) 8. 1/4 * (-3. 1/3) = 33/4 * (-10/3) = 11/2 * (-5/1) = -55/2

2) -55/2 * (-2. 2/15) = -55/2 * (-32/15) = -11/1 * (-16/3) = 176/3 = 58. 2/3

3) 1 - 67/69 = 69/69 - 67/69 = 2/69

4) 2/69 * 23/24 = 1/3 * 1/12 = 1/36

5) 58. 2/3 + 1/36 = 58. 24/36 + 1/36 =

58. 25/36
