分析:(1)根據(jù)乘法交換律進(jìn)行簡(jiǎn)算;
(2)根據(jù)乘法分配律進(jìn)行簡(jiǎn)算;
(3)根據(jù)乘法分配律進(jìn)行簡(jiǎn)算;
(4)根據(jù)乘法分配律進(jìn)行簡(jiǎn)算;
(5)根據(jù)乘法分配律進(jìn)行簡(jiǎn)算;
(6)1.02=1+0.02,然后再根據(jù)乘法分配律進(jìn)行簡(jiǎn)算.
解答:解:(1)0.8×0.94×12.5
=0.8×12.5×0.94
=10×0.94
=9.4;
(2)0.68×99+0.68
=0.68×(99+1)
=0.68×100
=68;
(3)0.48×8.5+0.48×1.5
=0.48×(8.5+1.5)
=0.48×10
=4.8;
(4)18.6×1.37-18.6×0.37
=18.6×(1.37-0.37)
=18.6×1
=18.6;
(5)18.8×101-18.8
=18.8×(101-1)
=18.8×100
=1880;
(6)1.02×6.5
=(1+0.02)×6.5
=1×6.5+0.02×6.5
=6.5+0.13
=6.63.
點(diǎn)評(píng):完成本題要注意分析式中數(shù)據(jù),運(yùn)用合適的簡(jiǎn)便方法計(jì)算.
