脱式计算,能简算的要简算.99×0.625+0.625 ...

(1)99×0.625+0.625=(99+1)×0.625=100×0.625=62.5;(2)88×125=11×8×125=11×(8×125)=11×1000=11000;(3)72×125=9×8×125=9×(8×125)=9×1000=9000;(4)250×13×4=(250×4)×13=1000×13=13000.

(1)99×0.625+0.625,=(99+1)×0.625,=100×0.625,=62.5;(2)(53.76-17.49)÷1.8,=36.27÷1.8,=20.15;(3)(0.8×7+4.56÷1.9)×12.5,=(5.6+2.4)×12.5,=8×12.5,=100;(4)15.73-(2.17+0.73)-1.83,=15.73-2.17-0.73-1.83,=(15....

我知道

36÷(0.625+0.275) =36÷0.9 =40

0.625×5.8+5/8×3.2+62.5% =0.625x5.8+0.625x3.2+0.625 =0.625x(5.8+3.2+1) =0.625x10 =62.5; 2017×2015/2016 =(2016+1)x2015/216 =2016x2015/2016+1x2015/2016 =2015+2015/2016 =2015又2015/2016; (1/2+1/3+1/6)x24 =1/2x24+1/3x24+1/6x24 =1...

6.25*0.23+17.7*0.625 =6.25*0.23+1.77*6.25 =6.25*(0.23+1.77) =6.25*2 =12.5

1、用竖式计算 0.396÷1.2= 0.756÷0.36= 15.6×13= 0.18×15= 0.025×14= 3.06×36= 0.04×0.12= 3.84×2.6≈ 5.76×3= (保留一位小数) 7.15×22 90.75÷3.3 3.68×0.25 16.9÷0.13 1.55÷3.9 3.7×0.016 13.76×0.8= 5.2×0.6 8.4×1.3 6.4×0.5 4.48×0.4 5.25...

0.625×0.8×0.04×0.5 =(0.625×0.8)×(0.04×5) =0.5×0.2 =0.1 你好,本题已解答,如果满意 请点右下角“采纳答案”。

脱式计算 4乘8分之5加62.5%乘7减0.625 =4x0.625+0.625x7-0.625 =(4+7-1)x0.625 =10x0.625 =6.25

6.25×0.32 +16.8×0.625 =6.25×0.32 +1.68×6.25 =6.25×(0.32+1.68) =6.25×2 =12.5
