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

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

=4.2x100+4.2x0.1 =4200+0.42 =4200.42

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

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

6.2×100.1=6.2×(100+0.1)=6.2×100+6.2×0.1=620+0.62=620.62

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

1乘1/100除以1/2000乘1/10 =1*1/100*2000*10 =1/10*2000 =200

(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
