48乘125简便运算??脱式

48×125 =6×8×125 =6×1000 =6000

30000

=1000x4÷125 =1000÷125x4 =8x4 =32

48乘99简便脱式计算 原式=48*99 =48*(99+1-1) =48*100-48 =4800-48 =4752

解:88x125 =8x125x11 =1000x11 =11000 分析:本题简便计算的关键在于要利用8x125=1000的常用式子,然后将88分解成8x11.而后就可算出结果是11000.

16乘以25乘以125 =2×8×25×125 =(2×25)×(8×125) =50×1000 =50000 供参考,有疑问请追问

125x64 =125x8x8 =1000x8 =8000
