分析:(1)根據(jù)乘法交換律簡(jiǎn)算;
(2)運(yùn)用乘法分配律簡(jiǎn)算;
(3)先算小括號(hào)里面減法,再運(yùn)用乘法分配律簡(jiǎn)算;
(4)先把16分解4×4,再根據(jù)乘法結(jié)合律簡(jiǎn)算;
(5)按照從左到右的順序計(jì)算;
(6)根據(jù)加法交換律簡(jiǎn)算.
解答:解:(1)125×23×8
=125×8×23
=1000×23
=23000;
(2)46×64+64×54
=64×(46+54)
=64×100
=6400;
(3)(567-462)×24
=105×24
=(100+5)×24
=100×24+5×24
=2400+120
=2520;
(4)15×27×16
=15×27×(4×4)
=(15×4)×(27×4)
=60×108
=6480;
(5)6.25+3.52-0.65
=9.77-0.65
=9.12;
(6)16.8+36.7+33.2
=16.8+33.2+35.7
=50+35.7
=85.7.
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.
