18/5×6×2016/2017 简便算法

18/5×6×2016/2017 =(18/5×6)×2016/2017 =3/5×2016/2017 =6048/10085

960÷[(18+6)×5] =960÷【24×5】 =960÷120 =8 直接算最简便

3/5×18.8+5.2×0.6+0.6 =0.6x18.8+0.6x5.2+0.6x1 =0.6x(18.8+5.2+1) =0.6x25 =15

/18×5.4+7.6÷18/7+7/18+1/5用简便方法 解:根据分配律, 原式=7/18x5.4+7.6x7/18+7/18+1/5 =7/18x(5.4+7.6+1)+1/5 =7/18x14+1/5 =49/9+1/5 =5+4/9+1/5 =5+20/45+9/45 =5又29/45

1/6×5/13+2/9+5/13+6/18×5/13,换分子,全部换成13/5的,剩下的我不多说,应该会了吧

简便运算 3/20-5/18+7/20-1/18 =(3/20+7/20)-(5/18+1/18) =1/2-1/3 =1/6

列式计算为 936÷(6×90) =936÷6÷90 =156÷90 =26/15 所以原式的计算结果为26/15.

62×4+44×5+5×18 =62×4+(44+18)×5 =62×4+62×5 =62×(4+5) =62×9 =62×10-62×1 =620-62 =558

18×(1/3+9分之5-1/6) =18×3分之1+18×9分之5-18×6分之1 =6+10-3 =13 结果是13
