巧算:125x64x25x5

125x8x5x8x25 =1000x40x25 =1000x1000 =1000000

解:原式=125×8×2×4×25 =1000×100×2 =200000 来自筠凊学习小组(数学分队) 求采纳

125x48x25=125×8×6×25=1000×150=150000

如图

4x(125x25) =4×25×125 =100×125 =12500

可以

14×25=10×25+4×25=250+100=350; 18×125=10×125+8×125=1250+1000=2250; 24×25=20×25+4×25=500+100=600

6X44X25 =6X11X4X25 =66X100 =6600

10000÷(125x25) =10000÷(5x25x25) =10000÷5÷25÷25 =2000÷25÷25 =80÷25 =16/25

原数等于 8×25+17×25 =200+425 =625 ~回答完毕~ ~结果仅供参考~ ~\(^o^)/~祝学习进步~~~
