解:(1)6.3×60%+4.7×60%-0.6,
=60%×(6.3+4.7-1),
=60%×10,
=6;
(2)0.25×13×4×
,
=(0.25×4)×(13×
),
=1×1,
=1;
(3))(13.62-8.4×1.05)÷0.32,
=(13.62-8.82)÷0.32,
=4.8÷0.32,
=15;
(4)11×11×11-11×11-10,
=11×11×(11-1)-10,
=121×10-10,
=10×(121-1),
=10×120,
=1200;
(5)1.5×[0.02÷(2.1-2.09)],
=1.5×[0.02÷0.01],
=1.5×2,
=3.
分析:(1)化0.6=60%,運(yùn)用乘法分配律解答,
(2)運(yùn)用乘法交換律和乘法結(jié)合律解答,
(3)先算括號(hào)里的8.4×1.05=8.82,再算括號(hào)里13.62-8.82=4.8,最后算4.8÷0.32解答,
(4)運(yùn)用乘法分配律解答,
(5)先算小括號(hào)里2.1-2.09=0.01,再算中括號(hào)里0.02÷0.01=2,最后算1.5×2解答.
點(diǎn)評(píng):本題主要考查學(xué)生對(duì)于四則運(yùn)算計(jì)算方法以及簡(jiǎn)便運(yùn)算定律掌握.
