101×37.8%1.25×37.8×0.8用简便方法计算

37.8÷1.25×0.8(可以用简便算法吗?) 37.8÷1.25×0.8 =37.8*0.8*(1/1.25) =37.8*0.8/0.8 =37.8

本题直接计算最简便 解: 37.8÷1.25×0.8 =30.24×0.8 =24.192 结果是24.192

37.8/(1.25*8/10) =37.8/(10/10) =37.8/1 =37.8

37.8÷1.25×0.8=37.8除以括号1.25乘以0.8括起来。(错)

1.25x8.37x0.8 =1.25x0.8x8.37 =1x8.37 =8.37 望采纳

(1)0.25×32×1.25=(0.25×4)×(8×1.25)=1×10=10;(2)47×8.17+37×8.17=8.17×(47+37)=8.17×1=8.17;(3)920÷[12×(25+45)]=920÷(12×65)=920÷35=34;(4)215÷[1?(15÷13)]=215÷(1?35)=215÷25=13.

1.25×37×8 =1.25×8×37 =10×37 =370

37.8×1.25×0.8 =37.8×(1.25×0.8) =37.8×1 =37.8

6.25*8.37*16+3.75*0.837*8 =1.25*5*8.37*8*2+1.25*3*0.875*8 =(1.25*8)*(2*5)*8.75+(1.25*8)*3*0.875 =10*10*8.75+10*3*0.875 =100*8.75+30*0.875 =875+26.25 =901.25
