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

4.8x100.1 =4.8x(100+0.1) =4.8x100+4.8x0.1 =480+0.48 =480.48

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”。

5.28×100.1用脱式计算怎么简算 5.28×100.1 =5.28*(100+0.1) =5.28*100+5.28*0.1 =528+0.528 =528.528

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

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

1×1/100÷1/2000×1/10 =1×1/100×2000×1/10 =2

(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

(1)0.97×100.1 =0.97×(100+0.1)=0.97×100+0.1×0.97=97+0.097=97.097(2)7.2÷4.5=7.2÷(9×0.5)=7.2÷9÷0.5=0.8÷0.5=1.6(3)0.25×5.5×32=0.25×5.5×8×4=(0.25×4)×(5.5×8)=1×44=44(4)9.9+0.1-9.9+0.1=(9.9-9.9)+(0.1+0.1)=0.2

=(100+0.1)✘0.45 =100✘0.45+0.1✘0.45 =45+0.045 =45.045
