分析:(1)按從左到右的順序計(jì)算;
(2)根據(jù)商不變規(guī)律,被除數(shù)和除數(shù)同時(shí)擴(kuò)大8倍,然后再計(jì)算;
(3)運(yùn)用加法結(jié)合律簡(jiǎn)算;
(4)先算小括號(hào)里面的除法,再算小括號(hào)里面的加法,最后算括號(hào)外的乘法;
(5)把32分解成4×8,然后使用乘法結(jié)合律簡(jiǎn)算;
(6)先把333×444變成666×222,然后使用乘法分配律簡(jiǎn)算.
解答:解:(1)16.2-4.65+5.35,
=11.55+5.35,
=16.9;
(2)6000÷125,
=(6000×8)÷(125×8),
=48000÷1000,
=48;
(3)13.7-6.38+6.3-4.32,
=(13.7+6.3)-(6.38+4.32),
=20-10.7,
=9.3;
(4)(45+405÷27)×120,
=(45+15)×120,
=60×120,
=7200;
(5)125×250×32,
=125×250×4×8,
=(125×8)×(250×4),
=1000×1000,
=1000000;
(6)333×444+666×778,
=666×222+666×778,
=666×(222+778),
=666×1000,
=666000.
點(diǎn)評(píng):此題是考查四則混合運(yùn)算,要仔細(xì)觀察算式的特點(diǎn),靈活運(yùn)用一些定律進(jìn)行簡(jiǎn)便計(jì)算.
