13. express 14/-5

14. Express13/-8

Answer 1

Answer:

1. -12/13

-12×4=-48

13×4=52

thus -12/13=-48/52

-12×-5=60

13×5=65

thus -12/13=60/65

2. -8×2= -16

11×2=22

8×5=40

-11×5 = -55

because minus sign could be moved from denominator to numerator or from numerator to denominator.

3. 14×4=56

-5×4=-20

-14×5=-70

5×5=25

the same as the before explanation.

4.13×5=65

-8×5=-40

13×-4=-52

-8×-4=32
