Răspuns:

$1. 804:I=2= > I=804:2= > I=402\\\\\\2. D:54=14rest26\\\\D=54*14+26= > D=782\\\\\\3.(a+25)*10=470\\\\a+25=470:10\\\\a=47-25= > a=2\\\\\\100*(c:7+175:5)=6300\\\\c:7+35=6300:100\\\\c:7=63-35\\\\c=28*7= > c=196\\\\\\(b:10):9=17 rest 6\\\\b:10=9*17+6\\\\b=159*10\\\\b=1590\\\\\\(240:10*37):d=7rest6\\\\888:d=7rest6\\\\888=7d+6\\\\888-6=7d= > d=882:7= > d=126$
