Answer 2

Ответ:

Пошаговое объяснение:

3.

1) 6. 3/8 - 2. 3/4 = 6. 3/8 -

2. 6/8 = 5. 11/8 - 2. 6/8 =

3. 5/8

2) 3. 5/8 * (-4) = 29/8 * (-4) = 29/2 * (-1) = -29/2 = -14. 1/2

3) 7/18 * 9 = 7/2 * 1 = 7/2 =

3. 1/2

4) -14. 1/2 + 3. 1/2 = -11

4.

1) 4. 1/3 - 8 = 4. 1/3 - 7. 3/3 = -3. 2/3

2) 9. 1/6 : (-3. 2/3) = 55/6 : (-11/3) = 55/6 * (-3/11) = 5/2 * (-1/1) = -5/2 = -2. 1/2

3) 24 * 3/8 = 72/8 = 9

4) -2. 1/2 + 9 = -2. 1/2 + 8. 2/2 = 6. 1/2
