0.125x16用简便方法计算怎么写

0.125x16 =0.125x8x2 =1x2 =2

把8和2 8与0.125乘 2与2.5乘 乖乖,怎么在空间里发算术啦?

道题(0.25 0.125)x16 =(0.25x4)x(0.125x4) =1x1/2 =1/2

125X50x16 =125x50x8x2 =(125x8)x(50x2) =1000x100 =100000 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

0.125x16.2x2.4 =0.125x16.2x8x0.3 =(0.125x8)x(16.2x0.3) =1x4.86 =4.86

54X125X16X8X625 =54X(125X8)X(2X8X5X125) =54X1000X10X1000 =540000000

125x16x5 =125x8x2x5 =(125x8)x(2x5) =1000x10 =10000

对的 125*16=125*(8*2) 125*16=125*16

400/(125-85)*16 =400/40*16 =10*16 =160
