第一题:53.5*35.3+53.5*43.2+78.5*46.5第二题:235*12.1+235*42.2-135*54.3
第三题:3.75*735-8分之3*5730+16.2*62.5 谁能把三道题解出来我怒赞

7850 5430 1620算式=53.5*(35.3+43.2)+78.5*46.5=78.5*(53.5+46.5)=7850 =235*(12.1+42.2)-135*54.3=54.3*(235-135)=5430 =3.75*735-3.75*573+16.2*62.5=3.75*(735-573)+16.2*62.5=37.5*16.2+16.2*62.5=16.2*100=1620
