分析:(1)同時(shí)運(yùn)算除法和乘法,再算減法;
(2)先把202分解成200+2,再運(yùn)用乘法分配律簡(jiǎn)算;
(3)(6)運(yùn)用乘法分配律簡(jiǎn)算;
(4)先把160分解成40×4,再運(yùn)用乘法結(jié)合律簡(jiǎn)算;
(5)先算小括號(hào)里面的減法,再根據(jù)除法的性質(zhì)簡(jiǎn)算.
解答:解:(1)2400÷80-14×2,
=30-28,
=2;
(2)43×202,
=43×(200+2),
=43×200+43×2,
=8600+86,
=8686;
(3)185×38+15×38,
=(185+15)×38,
=200×38,
=7600;
(4)160×25,
=40×4×25,
=40×(4×25),
=40×100,
=4000;
(5)420÷[(205-198)×4],
=420÷[7×4],
=420÷7÷4,
=60÷4,
=15;
(6)96×101-96,
=96×(101-1),
=96×100,
=9600.
點(diǎn)評(píng):完成本題要注意分析式中數(shù)據(jù),運(yùn)用合適的簡(jiǎn)便方法計(jì)算.
