分析:算式(1)把除數(shù)轉(zhuǎn)化為乘它的倒數(shù),再運(yùn)用乘法分配律進(jìn)行簡(jiǎn)算;
算式(2)運(yùn)用加法交換律和結(jié)合律進(jìn)行簡(jiǎn)算;
算式(3)按照分?jǐn)?shù)四則混合運(yùn)算的運(yùn)算順序和分?jǐn)?shù)四則運(yùn)算的計(jì)算法則進(jìn)行計(jì)算;

點(diǎn)評(píng):此題主要考查分?jǐn)?shù)、小數(shù)四則混合運(yùn)算,注意運(yùn)算順序和計(jì)算法則,并且能夠式中數(shù)據(jù)的特點(diǎn)靈活選擇簡(jiǎn)便方法進(jìn)行進(jìn)行簡(jiǎn)算.
