7.2÷1.6×0.5的简便算法

列式计算为 7.2÷(1.6÷0.5) =7.2÷3.2 =2.25 所以原式的计算结果为2.25

7.2X0.5+7.2÷0.5 =3.6+14.4 =18

7、2x0、5+2、8÷5 =3、6+0、56 =3、6+0、4+0、16 =4、16

1. (0.2+6.37÷0.7)×0.5 =(0.2+9.1)×0.5 =9.3×0.5 =4.65

这个英文乘以0.5和除以二是同一个意思,所以呢,也可以合并同类项吗?所以呢最后的结果就是13.7-3.7的差,乘以0.5,最后那等于10×0.5等于5

7.2x0.26÷6.5的简便算法怎么算 7.2x0.26÷6.5 =7.2÷(6.5÷0.26) =7.2÷25 =0.288

见图

12.7×6/5-7.2÷(5/6)简算 =12.7x6/5+7.2x6/5 =(12.7+7.2)x6/5 =(20-0.1)x6/5 =20x6/5-0.1x6/5 =24-1/10x6/5 =24-3/25 =23又22/25
