分析:(1)0.25×372×4,根據(jù)乘法交換律和結(jié)合律簡(jiǎn)算;
(2)8.62-2.77-3.62,根據(jù)減法的運(yùn)算性質(zhì)簡(jiǎn)算;
(3)9.6×7.28+2.72×9.6,根據(jù)乘法分配律簡(jiǎn)算;
(4)12.32-5.75-4.25,根據(jù)減法的運(yùn)算性質(zhì)簡(jiǎn)算.
解答:解:(1)0.25×372×4
=372×(0.25×4)
=372×1
=372;
(2)8.62-2.77-3.62
=8.62-3.62-2.77
=5-2.77
=2.23;
(3)9.6×7.28+2.72×9.6
=9.6×(7.28+2.72)
=9.6×10
=96;
(4)12.32-5.75-4.25
=12.32-(5.75+4.25)
=12.32-10
=2.32.
故答案為:372、×、0.25、×、4;-、3.62、-、2.77;9.6、×、7.28、+、2.72;-、5.75、+、4.25
點(diǎn)評(píng):此題考查的目的是理解掌握乘法的運(yùn)算定律和減法的運(yùn)算性質(zhì),并且能夠靈活運(yùn)用這些運(yùn)算定律和運(yùn)算性質(zhì)進(jìn)行簡(jiǎn)便計(jì)算.
