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

0.01 解析: 1÷100=0.01 1÷10=0.1

3.86×10.1 =3.86×(10+0.1) =3.86×10+3.86×0.1 =38.6+0.386 =38.986

4分之1×4分之1÷4分之1×0.25 =(4分之1×0.25)×(4分之1÷4分之1) =16分之1×1 =16分之1

10.1x0.99 =(10+0.1)×0.99 =10×0.99+0.1×0.99 =9.9+0.099 =9.999

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

1/2 x2/3 x......100/101 =1/101 说明: 前面的分母与后面的分子相约 亲,不懂请追问,满意请采纳,谢谢你!

十三分之九除以一百加一百分之一乘十三分之四脱式计算 解: 9/13÷100+1/100×4/13 =9/13×1/100+1/100×4/13 =(9/13+4/13)×1/00 =1×1/100 =1/100

5.2×10.1 =5.2×10+5.2×0.1 =52+0.52 =52.52

4/5+3/8×4/3-3/10 =4/5+1/2-3/10 =8/10+5/10-3/10 =13/10-3/10 =1 (1-4/5×1/12)除以1/3 =(1-1/15)*3 =(14/15)*3 =14/5 【160%-(2/5+40%)】除以1/2 =(160%-4/5)*2 =(4/5)*2 =8/5 【3/4-(7/16-0.25)】×17/9 =(3/4-3/16)*(17/9) =(9/16...
