分析:(1)32=4×8,然后再根據(jù)乘法交換律和結(jié)合律進(jìn)行簡(jiǎn)算;
(2)根據(jù)加法交換律和結(jié)合律,以及減法的性質(zhì)進(jìn)行簡(jiǎn)算;
(3)根據(jù)乘法分配律進(jìn)行簡(jiǎn)算;
(4)根據(jù)減法的性質(zhì)進(jìn)行簡(jiǎn)算.
解答:解:(1)32×0.125×25
=(4×8)×0.125×25
=(4×25)×(8×0.125)
=100×1
=100;
(2)13.76-4.53+2.24-1.47
=(13.76+2.24)-(4.53+1.47)
=16-6
=10;
(3)65×10.2-6.5×2
=6.5×102-6.5×2
=6.5×(102-2)
=6.5×100
=650;
(4)15.84-2.17-2.83
=15.84-(2.17+2.83)
=15.84-5
=10.84.
點(diǎn)評(píng):考查了運(yùn)算定律與簡(jiǎn)便運(yùn)算,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)便計(jì)算.
