12.5x88的简便计算两种

12.5*88 的简便计算法二种1) (12.5*2*4)*11 = 11002) 12.5*(8+80) = 100+1000 = 11003) 100/8 * 88 = 11004) 10(1+1/4)*88 = 880+220 = 11005) .

12.5x88= 12.5x(80+8)= 12.5x80+ 12.5x8=1000+100=1100

=12.5*80+8=12.5*80+12.5*8=100+10=110

12.6x88 =(12.5+0.1)x88 =12.5x88+0.1x88 =12.5x8x11+8.8 =100x11+8.8 =1100+8.8 =1108.8 请采纳正确答案,你们只提问,不采纳正确答案,回答都没有劲!谢谢管理员推荐采纳!! 朋友,请【采纳答案】,您的采纳是我答题的动力,如果肌筏冠禾攉鼓圭态氦卡没有明白,请追问.谢谢.

把88拆成80+8,分配律分开乘

7.2x12.5用两种简便方法计算7.2x12.5=9*0.8*12.5=9*10=90

原式 =125x(8x11) =(125x8)x11 =1000x11 =11000 125x80+125x8 =10000+1000 =11000 (25x5)x(4x22) =(25x4)x(5x22) =100x110 =11000 供参考.

1.25*88=1.25*80+1.25*8=100+10=110~1.25*88=1*88+0.25*88=88+22=110

125*88=125*8*11=1000*11=11000

125x88的简便计算 解,:根据拆分法和结合律的运用,原式=125x8x11=1000x11=11000
