分析:①可根據(jù)乘法分配律計(jì)算;
②可根據(jù)一個(gè)數(shù)除以兩個(gè)數(shù),等于除以這兩個(gè)數(shù)的積的除法性質(zhì)計(jì)算;
③可根據(jù)加法交換律及一個(gè)數(shù)減兩個(gè)數(shù),等于減去這兩個(gè)數(shù)的和的減法性質(zhì)計(jì)算;
④可根據(jù)一個(gè)數(shù)減兩個(gè)數(shù)的差,等于減去兩個(gè)數(shù)中的被減數(shù),加上減數(shù)的減法性質(zhì)計(jì)算;
⑤⑥⑦根據(jù)四則混合運(yùn)算的運(yùn)算順序計(jì)算即可;
⑧可將88拆分為11×8后根據(jù)乘法結(jié)合律計(jì)算.
解答:解:①468×5+232×5
=(468+232)×5,
=700×5,
=3500;
②900÷25÷4
=900÷(25×4),
=900÷100,
=9;
③15.6-4.47-5.53+6.4
=15.6+6.4-(4.47+5.53),
=22-10,
=12;
④23.76-(5.76-4.23)
=23.76-5.76+4.23,
=18+4.23,
=22.23;
⑤19×96+962÷74
=1824+13,
=1837;
⑥400-(1300÷65+35)
=400-(20+35),
=400-55,
=345;
⑦6.75+0.5-4.86
=7.25-4.86,
=2.39;
⑧88×125
=11×(8×125),
=11×1000,
=11000.
點(diǎn)評(píng):完成本題要注意分析式中數(shù)據(jù)的特點(diǎn),能簡(jiǎn)便計(jì)算的要簡(jiǎn)便計(jì)算.
