解:(1)9.06-2.68-0.32,
=9.06-(2.68+0.32),
=9.06-3,
=6.06;
(2)(3.06÷0.25+2.76)×0.2,
=(12.24+2.76)×0.2,
=15×0.2,
=3;
(3)18-(
+4÷
),
=18-(0.6+4×
),
=18-(0.6+10),
=18-10.6,
=7.4;
(4)2.7×1.25+5.3×125%,
=2.7×1.25+5.3×1.25,
=(2.7+5.3)×1.25,
=8×1.25,
=10.
分析:(1)運(yùn)用減法的性質(zhì)簡(jiǎn)算;
(2)先算括號(hào)內(nèi)的除法,再算括號(hào)內(nèi)的加法,最后算括號(hào)外的乘法;
(3)先算括號(hào)內(nèi)的除法,再算括號(hào)內(nèi)的加法,最后算括號(hào)外的減法;
(4)把百分?jǐn)?shù)化為1.25,運(yùn)用乘法分配律簡(jiǎn)算.
點(diǎn)評(píng):此題考查了四則混合運(yùn)算,注意運(yùn)算順序和運(yùn)算法則,靈活運(yùn)用所學(xué)的運(yùn)算定律簡(jiǎn)算.
