4.8乘100.1脱式怎样计算

4.8乘100.1脱式怎样计算 =4.8x(100+0.1) =4.8x100+0.48 =480+0.48 =480.48

8.5X100.1 =8.5X(100+0.1) =8.5X100+8.5X0.1 =850+0.85 =850.85

3.28×100.1 =3.28×100+3.28×0.1 =328+0.328 =328.328

100.1x0.45 =(100+0.1)×0.45 =100×0.45+0.1×0.45 =45+0.045 =45.045

26.8×100.1 =26.8×(100+0.1) =26.8×100+26.8×0.1 =2680+2.68 =2682.68

0.89乘一百点一脱式计算 0.89乘一百点一 =0.89*(100+0.1) =0.89*100+0.89*0.1 =89+0.089 =89.89

38x(100-1) =38x100-38x1 =3800-38 =3762 希望能帮到你!

(首项加末项)乘以 项数 再一起除以二 这是等差数列的算法 (1+100 )*100/2=5050

4.4×(100-1) =4.4×100-4.4×1 =440-4.4 =435.6 你好,本题已解答,如果满意 请点右上角“采纳答案”。

3.14×20×100×1/3+3.14×100×30 =3.14×100×(20×1/3+30) =314×110/3 =11513又3分之1
