0.125×48(简算)

0.125×48 =0.125×8×6 =1×6 =6

48×0.25×0.125 =6×0.25×0.125x8 =1.5x1 =1.5

48×0.125 =8x0.125x6 =1x6 =6 祝天天向上。

0.125*8*6*0.5=3

0.375×48-0.125×24=15 ~回答完毕~ ~\(^o^)/~祝学习进步~~~

48X0.125X5 =(6X5)X(8X0.125) =30X1 =30

0.125×7.48×80 =(0.125×80)×7.48 =10×7.48 =74.8

9/0.125 =9*8 =72 =0.93×(1+0.01) =0.93×1+0.93...

原式 =48x(0.125x8) =48x1 =48

把48分解为8乘以6,再用结合率运算。
