Answer 1

Divide both number by thier greatest common divisor which is 3

1)

`( -15)/(12)` =
`( - 15 / 3)/(12 / 3)` =
`( - 5)/(4)`

2)

`(15)/( - 12)` =
`(15 / 3)/( - 12 / 3)` =
`(5)/( - 4)`

3)

`( - 15)/( - 12)` =
`( - 15 / 3)/( - 12 / 3)` =
`( - 5)/( - 4)` =
`(5)/(4)`

4)

`- (15)/(12)` =
`- (15 / 3)/(12 / 3)` =
`- (5)/(4)`

Answer 2

-15/12 = -1.25

15/-12 = -1.25

-15/-12 = 1.25

`-(15)/(12)` = -1.25
