please answers my questions​

Answer 1

Answer:

Step-by-step explanation:

2i) (4/9) / (-5/12)

= 4/9 x -12/5

= -16/15

ii) (-12/7) / (-18)

= -12/7 x -1/18

= 2/21

3i) (9/8) / x = (-3/2)

9/8 * 1/x = -3/2

9/8x = -3/2

Cross multiply

9 * 2 = -3 * 8x

18 = -24x

x= -18/24

= -3/4

ii) x / (-7/5) = 10/19

x * -5/7 = 10/19

-5x/7 = 10/19

Cross multiply

-5x * 19 = 7 * 10

-95x = 70

x = -70/95

x = - 14/19

4) 4/5 x (5/8 - 16/5)

4/5 x [(25 - 128)/40]

4/5 x -103/40

= -103/50
