0.65+9.9×6.5的简便计算方法

简便计算的过程为: 0.65+10.9×6.5 =6.5×(0.1+10.9) =6.5×11 =71.5 简便运算要求灵活、正确、合理地运用各种定义、定理、定律、性质、法则等等,改变原有的运算顺序进行计算,通过简便运算要大幅度地提高计算速度及正确率,使复杂的计算变得简...

0.65+9.9×6.5 =6.5*0.1+9.9*6.5 =6.5*(0.1+9.9) =6.5*10 =65

0.65+10.9×6.5 =0.65+109x0.65 =(1+109)x0.65 =110x0.65 =71.5

0.65+10.9X6.5 =6.5X(0.1+10.9) =6.5X11 =6.5X10+6.5X1 =65+6.5 =71.5

0.65+10.9x6.5 =0.65x1+109x0.65 =0.65x(1+109) =0.65x110 =71.5

0.65+10.9×6.5 =(0.1+10.9)×6.5 =11×6.5 =71.5 你好,本题已解答,如果满意 请点右上角“采纳答案”。

6.5×9.9+0.65 =6.5×9.9+6.5×0.1 =6.5×(9.9+0.1) =6.5×10 =65

0.654+10.9*6.5 =0.1*(6.5+0.04)+10.9*6.5 =(10.9+0.1)*6.5+0.004 =(10+1)*6.5+0.004 =65+6.5+0.004 =71.504, 这是简便运算的。

0.65+19.9×6.5 =0.1×6.5+19.9×6.5 =(0.1+19.9)×6.5 =20×6.5 =130

0.65✘10.9✘6.5简便计算 0.65✘10.9✘6.5 =6.976*6.5 =45.344 直接计算 没有简算
