分析:(1)可先將8.8拆分后運(yùn)用分配律進(jìn)行簡(jiǎn)算;
(2)可將32拆分后運(yùn)用結(jié)合律進(jìn)行簡(jiǎn)算;
(3)、(5)、(6)可據(jù)分配律進(jìn)行簡(jiǎn)算;
(4)可據(jù)連除相當(dāng)于除以兩個(gè)數(shù)的積進(jìn)行簡(jiǎn)算.
解答:解:(1)8.8×0.125
=(8+0.8)×0.125,
=8×0.125+0.8×0.125,
=1+0.1,
=1.1;
(2)2.5×1.25×32
=(2.5×4)×(1.25×8),
=10×10,
=100;
(3)7.6×5.3+3.7×7.6
=(5.3+3.7)×7.6,
=9×7.6,
=68.4;
(4)37÷0.25÷4
=37÷(0.25×4),
=37÷1,
=37;
(5)3.85×101-3.85
=(101-1)×3.85,
=100×3.85,
=385;
(6)(23+4.6)÷2.3
=23÷2.3+4.6÷2.3,
=10+2,
=12.
點(diǎn)評(píng):根據(jù)式中數(shù)據(jù)的特點(diǎn)將式中數(shù)據(jù)進(jìn)行拆分簡(jiǎn)算的方法在四則混合運(yùn)算中經(jīng)常用到.
