分析:(1)(3)可根據(jù)乘法分配律計(jì)算.
(2)可將101拆分為100+1后,再根據(jù)乘法分配律計(jì)算.
(3)可根據(jù)加法交換律及結(jié)合律計(jì)算.
(5)可根據(jù)交換律計(jì)算.
(6)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.
解答:解:(1)4×(500+25)
=4×500+4×25
=2000+100
=2100
(2)89×101
=89×(100+1)
=89×100+89
=8900+89
=8989
(3)4.25+67+5.75+133
=(4.25+5.75)+(67+133)
=10+200
=210
(4)37×99+37
=(99+1)×37
=100×37
=3700
(5)36.54-0.95-6.54
=36.54-6.54-0.95
=30-0.95
=29.05.
(6)1800÷25÷4
=1800÷(25×4)
=1600÷100
=16.
點(diǎn)評(píng):完成本題要注意分析式中數(shù)據(jù)的特點(diǎn),然后運(yùn)用合適的方法計(jì)算.
