分析:(1)可根據(jù)加法交換律計(jì)算;
(2)可根據(jù)一個(gè)數(shù)減兩個(gè)數(shù),等于用這個(gè)數(shù)減去這兩個(gè)數(shù)的積的減法性質(zhì)計(jì)算;
(3)可根據(jù)加法交換律及結(jié)合律計(jì)算;
(4)可根據(jù)一個(gè)數(shù)除以?xún)蓚(gè)數(shù),等于用這個(gè)數(shù)除以這兩個(gè)數(shù)的積的除法性質(zhì)計(jì)算;
(5)可將32拆分為8×4后根據(jù)乘法結(jié)合律計(jì)算;
(6)可根據(jù)乘法分配律計(jì)算.
解答:解:(1)548+468+52
=(548+52)+468,
=600+468,
=1068;
(2)9.14-1.43-4.57
=9.14-(1.43+4.57),
=9.14-6,
=3.14;
(3)77+2.7+2.3+23
=(77+23)+(2.7+2.3),
=100+5,
=105;
(4)3200÷4÷25
=3200÷(4×25),
=3200÷100,
=32;
(5)125×32×25
=(125×8)×(4×25),
=1000×100,
=100000;
(6)2009×95+5×2009
=2009×(95+5),
=2009×100,
=200900.
點(diǎn)評(píng):完成本題要注意分析各小題中數(shù)據(jù)的特點(diǎn),然后運(yùn)用合適的方法進(jìn)行簡(jiǎn)算.
