1) (15/20+1/20) * 1 = 16/20

2) (7/12-4/12) * 16/19=3/12*16/19=1/4*16/19=4/19

3) (73/5-24/15) * 9/32 = (219/15-24/15) * 9/32 = 204/15*9/32 = 153/40 = 3 23/40

4) (11/24+4/24) * 13/5 = 15/24*13/5 = 39/24 = 1 15/24

5) (255/10+46/10) * 5/9 = 301/10*5/9=301/18 = 16 13/18

6) (112/16-25/16) * 4/25 = 87/16*4/25=87/100=0,87
