分析:(1)可將102拆分為100+2后根據(jù)乘法分配律計算;
(2)可將4.8拆分為4×1.2后計算;
(3)可將4.25×3.7變?yōu)?2.5×0.37后根據(jù)乘法分配律計算;
(4)可將式中的除法算式變?yōu)槌朔ㄋ闶胶,根?jù)乘法分配律計算;
(5)可根據(jù)一個數(shù)減兩個數(shù)的差,等于減去兩個數(shù)中的被減數(shù),加上減數(shù)的減法性質(zhì)計算;
(6)可將101拆分為100+1后根據(jù)乘法分配律計算.
解答:解:(1)102×4.5
=(100+2)×4.5,
=100×4.5+2×4.5,
=450+9,
=459;
(2)0.25×4.8
=0.25×4×1.2,
=1×1.2,
=1.2;
(3)4.25×3.7-0.37×32.5
=42.5×0.37-0.37×32.5,
=(42.5-32.5)×0.37,
=10×0.37,
=3.7;
(4)5.23×4+4.77÷0.25
=5.23×4+4.77
÷,
=5.23×4+4.77×4,
=(5.23+4.77)×4,
=10×4,
=40;
(5)6.67-(4.54-3.33)
=6.67+3.33-4.54,
=10-4.54,
=5.46;
(4)28.6×101-28.6
=28.6×(100+1)-28.6,
=28.6×100+28.6×1-28.6,
=2860+(28.6-28.6),
=2860+0,
=2860.
點評:完成本題要注意分析式中數(shù)據(jù)的特點,運(yùn)用合適的方法進(jìn)行計算.
