125除以括号五零除以八用简便方法怎么算

列式为: 125➗(5➗8) =125➗5x8 =125x8➗5 =1000➗5 =200

12.5÷(50÷8) =12.5×8÷50 =100÷50 =2

40x(70x50) =40x50x70 =2000x70 =140000

(520+480)÷50×4 =1000÷50×4 =20×4 =80

116-(50÷25+8x2) =116-(2+16) =116-16-2 =100-2 =98

没有简便方法,直接计算就好 72-括号20.5+750除以50反括号 =72-(20.5+15) =72-35.5 =36.5 行家正解,不明白可以追问!祝您学习进步 满意请点击下面的【选为满意回答】按钮,O(∩_∩)O谢谢

150÷(50-35)x35 =150÷15x35 =10x35 =350 直接计算最简便

5400÷(50×7) =5400÷50÷7 =(5400×2)÷(50×2)÷7 =10800÷100÷7 =108÷7 =7分之108
