a) 20/9 : 8/3 =

= 20/9 * 3/8

= 5/6

b) -10/7 : 25/21 =

= -10/7 * 21/25

= -6/5

c) -16/27 : ( -4/9 ) =

= -16/27 * ( -9/4 )

= 4/3

d) 125/12 : ( -100/9 ) =

= 125/12 * ( -9/100 )

= -15/16

e) -3 3/15 : ( -1 2/25 ) =

= -48/15 : ( -27/25 )

= -48/15 * ( -25/27 )

= 80/27

f) 24 : ( -36/7 ) =

= 24/1 * ( -7/36 )

= -14/3
