脱式计算;1乘1/100除以1/2000乘1/10 = = = = ??...

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

0.01 解析: 1÷100=0.01 1÷10=0.1

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

1/2 x2/3 x......100/101 =1/101 说明: 前面的分母与后面的分子相约

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

4.4×(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”。

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

(1)0.01+1.01×99,=0.01+1.01×(100-1),=0.01+1.01×100-1.01×1,=101+0.01-1.01,=100;(2)26×20.2-8.4-1.8,=26×(20+0.2)-(8.4+1.8),=520+5.2-10.2,=525.2-10.2,=515;(3)89.3×43+38×89.3+893×1.9,=89.3×43+38×89.3+89.3×19,=...

(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

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