解:(1)0.25×32×12.5%,
=(0.25×4)×(8×0.125),
=1×1,
=1;
(2)3.7×0.32+3.2×0.63,
=3.7×0.32+0.32×6.3,
=(3.7+6.3)×0.32,
=10×0.32,
=3.2;
(3)(

=12+10-8,
=14.
分析:(1)0.25×32×12.5%,将原式转化为:0.25×4×8×0.125,然后运用乘法结合律进行简算;
(2)3.7×0.32+3.2×0.63,根据因数与积的不变规律,将原式转化为:3.7×0.32+0.32×6.3,再应用乘法分配律进行简算;
(3)(
+
-
)÷
.把除数转化为乘它的倒数,再运用乘法分配律进行简算.
点评:此题考查的目的是理解掌握乘法结合律、乘法分配律的意义,并且能够灵活运用这些运算定律对小数四则混合运算进行简便计算.
