0.765×10.8-76.5×0.008的简便算法

原式=76.5x(0.108-0.008)=76.5x0.1=7.65

0.765*10.8-76.5*0.008 =0.765*10.8-0.765*0.8 =0.765*(10.8-0.8) =0.765*10 =7.65

0.765×10.8-76.5×0.008 =0.765×10.8-0.765×0.8 =0.765×(10.8-0.8) =0.765×10 =7.65

解:根据拆分法我提取公因式的运用 原式=0.765x10.8-76.5x0.008 =0.765x10.8-0.765x0.8 =0.765x(10.8-0.8) =0.765x10 =7.65
