简便计算125➗20乘以8

926➗125用简便方法算 926➗125 =(1000-74)➗125 =1000➗125-74➗125 =8-0.592 =7.408

解:简便计算 2000➗125 =2x1000÷125 =2x(1000÷125) =2x8 =16 49500➗500 =495÷5 =99 祝天天向上。

74000÷(125×37) =(74÷37)×(1000÷125) =2×8 =16。

解:9000000➗25➗125➗8➗5➗4➗2 =9000000➗(25x125x8x5x4x2) =9000000➗(25x4x5x2x125x8) =9000000➗(100x10x1000) =9

=125➗(5x5) =125➗25 =5

420➗5 =(400+20)➗5 =400➗5+20➗5 =80+4 =84

简便计算: 80➗16 =80➗8➗2 =10➗2 =5

(8.25-37.5)➗2.5➗4 =(8.25-37.5)➗(2.5x4) =-29.25➗10 =-2.925

72➗4.8 =72➗(6×0.8) =72➗6➗0.8 =12➗0.8 =15

6.8÷0.17×1.6 =0.68÷0.17×16 =4×16 =64 7.08-0.8×1.25 =7.08-(4/5)×(5/4) =7.08-1 =6.08 65.8÷9.4+12.9 =7+12.9 =19.9
