分析:(1)根據(jù)減法的性質(zhì)簡(jiǎn)算;
(2)把分?jǐn)?shù)化成小數(shù),然后同時(shí)運(yùn)算乘法,再算減法;
(3)先算小括號(hào)里面的乘法,再算小括號(hào)里面的減法,最后算括號(hào)外的除法;
(4)先算小括號(hào)里面的加法,再算中括號(hào)里面的減法,最后算括號(hào)外的除法;
(5)(6)先把除法變成乘法,再運(yùn)用乘法分配律簡(jiǎn)算.
解答:解:(1)7.32-(3.8+1.32),
=7.32-1.32-3.8,
=6-3.8,
=2.2;
(2)95.6×18-
×8,
=95.6×18-190.6×8
=1720.8-1524.8,

(4)1.5÷[1.2-(0.4+0.5)],
=1.5÷[1.2-0.9],
=1.5÷0.3,
=5;
(5)0.125×2+6.6÷8-12.5%,
=0.125×2+6.6×0.125-0.125,
=0.125×(2+6.6-1),
=0.125×7.6,
=0.125×8×0.95,
=1×0.95,
=0.95;
(6)6.7×0.25+9.3÷4,
=6.7×0.25+9.3×

點(diǎn)評(píng):本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)算定律進(jìn)行簡(jiǎn)便計(jì)算.
