分析:(1)運(yùn)用乘法的分配律進(jìn)行簡算;
(2)運(yùn)用除法的性質(zhì)進(jìn)行簡算;
(3)運(yùn)用乘法的分配律進(jìn)行簡算;
(4)把64化成8×8,再乘法的結(jié)合律進(jìn)行簡算;
(5)運(yùn)用乘法的分配律進(jìn)行簡算;
(6)運(yùn)用乘法的分配律進(jìn)行簡算.
解答:解:(1)95.6×1.8+0.18×44
=956×0.18+0.18×44
=(956+44)×0.18
=1000×0.18
=180;
(2)87.5÷12.5÷8
=87.5÷(12.5×8)
=87.5÷100
=0.875;
(3)0.125+3.7×
+
×5.3
=
×(1+3.7+5.3)
=
×10
=1.25;
(4)0.25×64×1.25
=0.25×8×8×1.25
=(0.25×8)×(8×1.25)
=2×10
=20;
(5)83×101
=83×(100+1)
=83×100+83×1
=8300+83
=8383;
(6)7.7×7+7.7+2×7.7
=7.7×(7+1+2)
=7.7×10
=77.
點(diǎn)評(píng):本題主要考查了學(xué)生在四則混合運(yùn)算中靈活運(yùn)用簡便算法的計(jì)算能力.
