解:(1)8.27+5.84+1.73+2.16,
=(8.27+1.73)+(5.84+2.16),
=10+8,
=18.
(2)18.51-9.08-0.92,
=18.51-(9.08+0.92),
=18.51-10,
=8.51.
(3)528÷6×5-432,
=88×5-432,
=440-432,
=8.
(4)282×5+18×5,
=(282+18)×5,
=300×5,
=1500.
(5)75+360÷20+15,
=75+18+15,
=(75+15)+18,
=90+18,
=108.
(6)(641-341)÷25×4,
=300÷25×4,
=12×4,
=48.
分析:(1)利用加法交換律將原式變形為(8.27+1.73)+(5.84+2.16),再進(jìn)行計(jì)算即可;
(2)先將原式變形為18.51-(9.08+0.92),再進(jìn)行計(jì)算即可;
(3)先進(jìn)行除法計(jì)算,再進(jìn)行乘法運(yùn)算,最后進(jìn)行減法運(yùn)算;
(4)先將原式變形為(282+18)×5,再進(jìn)行計(jì)算即可;
(5)先進(jìn)行除法計(jì)算,再進(jìn)行加法運(yùn)算;
(6)先進(jìn)行括號(hào)中的減法運(yùn)算,再進(jìn)行除法運(yùn)算,最后進(jìn)行乘法運(yùn)算.
點(diǎn)評(píng):此題主要考查小數(shù)四則混合運(yùn)算的方法,能簡(jiǎn)便的要進(jìn)行簡(jiǎn)便運(yùn)算.
