-12ц

12/5ц

Answer 2

Давайте вычислим каждое из данных выражений:

1. (-3/4) : 1ц 1/2 = -3/4 : 3/2 = -(3/4) * (2/3) = -1/2

2. 4 : (-1/2) = 4 * (-2) = -8

3. 5 : (-5/8) = 5 * (-8/5) = -8

4. (-5/6) : (-5/12) = (-5/6) * (-12/5) = 2

5. -3ц 3/4 : 1ц 1/2 = -(3 + 3/4) : (1 + 1/2) = -(15/4) : (3/2) = -(15/4) * (2/3) = -5/2

6. (-4ц 2/3) : 2/9 = -(4 + 2/3) : (2/9) = -(14/3) : (2/9) = -(14/3) * (9/2) = -21

7. (-6ц 1/4) : (-5/8) = -(6 + 1/4) : (-5/8) = -(25/4) : (-5/8) = (25/4) * (8/5) = 10

Итак, результаты вычислений:

1. -1/2
2. -8
3. -8
4. 2
5. -5/2
6. -21
7. 10
