Question

1) (3/4 + 1/20) * 1/2 2) (7/12 - 1/3) * 16/19 3) (7 3/5 - 2 4/15) * 9/32 4) (11/24 + 1/6) * 1 3/5 5) (5 1/2 + 2 3/5) * 5/9 6) (7 - 2 5/16) * 4/25

Answer 1

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
