(- 3/8) . 4/6 = - 12/48 = - 6/24 = - 3/12 = - 1/4

[(- 5/6) . 4/9] : 2/6 = -20/54 : 2/6 = - 120/108 = - 60/54 = - 30/27 = - 10/9

[7/5 : (- 2/4) ]. [ 9/5 : 7/2 = - 28/10 . 18/35 = - 504/350 = - 252/175 = - 36/25

[ (- 2/3) . ( - 2/4)] : [ 3/8 . (- 2/6) ] = 4/12 : - 6/48 = - 196/72 = - 98/ 36 = - 49/18

[ ( - 7/5) :  4/5] . 12/7 = - 35/20 .12/7 = - 420/140 = - 210/70 = - 105/ 35 = - 21/7 = - 3/1 = - 3
