32.7×0.35+0.65×32.7    
10.1×89
3.56×25.9-3.56×5.9    
 48×0.25.

解:(1)32.7×0.35+0.65×32.7,
=32.7×(0.35+0.65),
=32.7×1,
=32.7;
 
(2)10.1×89,
=(10+0.1)×89,
=10×89+0.1×89,
=890+8.9,
=898.9;

(3)3.56×25.9-3.56×5.9,
=3.56×(25.9-5.9),
=3.56×20,
=71.2;
  
 (2)48×0.25,
=12×4×0.25,
=12×(4×0.25),
=12×1,
=12.
分析:(1)(3)運(yùn)用乘法分配律簡(jiǎn)算;
(2)把10.1看作10+0.1,運(yùn)用乘法分配律簡(jiǎn)算;
(4)把48看作12×4,運(yùn)用乘法結(jié)合律簡(jiǎn)算.
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.
