Answer 1

2 supra 5 impartit la 6 supra 10  =   2/5*6/10= 2/3
12 supra 35 impartit la 36 supra 49  = 12/35*49/36= 7/15
11 supra 13 impartit la 33 supra 42  =  11/13*42/33=42/39=14/13
36 supra 35 impartit la 48 supra 49  = 36/35*49/48= 7/20

unde: /- impartirea
          *-imultirea

Answer 2

2/5:6/10=2/5•10/6=2/3.
12/35:36/49=12/35•49/36=7/15.
11/13:33/42=11/13•42/33=42/39=14/13.
36/35:48/49=36/35•49/48=6/5•7/8=3/5•7/4=21/20.
