18/3*rd2=6/rd2 (am rd2) =6*rd2/2=3*rd2

45/5*rd3=9/rd3 (am rd3) =9*rd3/3=3*rd3

36/4*rd3=9/rd3 (am rd3) =9*rd3/3=3*rd3

24/2*rd6=12/rd6 (am rd6) =12*rd6/6=2*rd6

6/3*rd2=2/rd2 (am rd2) =2*rd2/2=rd2

15/rd3 (am rd3) =15*rd3/3=5*rd3

b)28/4*rd7=7/rd7 (am rd7) =7*rd7/7=rd7

24/4*rd6=6/rd6 (am rd6) =6*rd6/6=rd6

18/6*rd3=3/rd3 (am rd3) =3*rd3/r=rd3
