解:(1)89.3×43+38×89.3+893×1.9,
=89.3×43+38×89.3+89.3×19,
=89.3×(43+38+19),
=89.3×100,
=8930;
(2)10.01×101-10.01,
=10.01×(101-1),
=10.01×100,
=1001;
(3)4.75×17.5+2.5×4.75,
=4.75×(17.5+2.5),
=4.75×20,
=95;
(4)1.25×32×0.25,
=1.25×8×4×0.25,
=(1.25×8)×(4×0.25),
=10×1,
=10;
(5)0.22×1.5+1.541÷2.3,
=0.33+0.67,
=1;
(6)(5.15-3.25)×0.4+0.36,
=1.9×0.4+0.36,
=0.76+0.36,
=1.12.
分析:(1)根據(jù)數(shù)字特點,把原式變?yōu)?9.3×43+38×89.3+89.3×19,運用乘法分配律簡算;
(2)(3)運用乘法分配律簡算;
(4)把32看作8×4,運用乘法結(jié)合律簡算;
(5)先算乘除,再算加法;
(6)先算括號內(nèi)的,再算括號外的乘法,最后算加法.
點評:此題考查了小數(shù)的四則混合運算,注意運算順序和運算法則,靈活運用所學(xué)的運算律簡便計算.
