Step-by-step explanation:

change the fractions into like fraction at first ...

to change this into like fraction at first find thier LCM

LCM of 9,8 is 72

after it multiply by the number so that the denominator be 72

7/-9×8/8= -56/72

-5/8×9/9= -45/72

so now it is clear that -45/72 is greater than -56/72

so -5/8 is greater than -7/9

---------------------------------------

do it for all

-4/5×8/8= -32/40

-7/8×5/5= -35/40

so, -4/5>-7/8

------------------------------

-9/13×12/12= -108/156

-7/12×13/13= -91/156

-7/12>-9/13
