72除4.8的简便计算???????

72÷4.8 =72÷24/5 =72*5/24 =15 确定,就是这个样,好好想想吧

完美解答,高速旋转的思维 72除以4.8 72/24/0.2(4.8拆成24,0.2) =72/8/3/0.2(24拆成8,3) =72/8/3x5【除以0.2,转化成除以1/5,再化成x5】 =(9/3)x5 =3x5 =15

72÷4.8 =12*6÷0.8÷0.6 =12÷0.8*6÷6 =12*5/4*1 =15

72/4.8 =72/12/0.4 =6/0.4 =15

72/4.8 =720/48 =180/12 =45/3 =15 ==================================== |【真实】【准确】【快速】【完美】| ==================================== 不懂请追问,解决请【采纳为最佳答案】,答题不易,谢谢支持!

(法一) 4.8/2.5/4 =4.8/(2.5*4) =4.8/10 =0.48 (法二) 4.8/2.5/4 =4.8/4/2.5 =1.2/2.5(同乘40,因为可以造成某数分之100的结果,在除法上只要考虑小数点的位置而已) =48/100 =0.48

如图

72➗4.8 =72➗(6×0.8) =72➗6➗0.8 =12➗0.8 =15

4.8/8+6.4/8=1.4
