3/1.25/0.4/0.25/8怎样简算

0.25x1.25x0.4x8 =0.25x0.4x1.25x8(乘法交换律) =0.1x100 =10

1000/0.14/1.25/8/0.25的简便算法 1000/0.14/1.25/8/0.25 =1000÷【(1.25*8)*(0.14*0.25)】 =1000÷(10*0.035) =2000/7

(0.4×0.25)×(1.25×0.8) =1×10=10

0.25×(8+0.4)×1.25 =0.25x8.4x1.25 =2.1x1.25 =2.625 (请采纳)

0.25×8×0.4×0.4×1.25 =(0.25×0.4)×(8×1.25) =0.1×10 =1

0.25×3.2×1.25 =0.25×4×0.8×1.25 =(0.25×4)×(0.8×1.25) =1×1 =1 你好,很高兴为你解答,希望对你有所帮助,若满意请及时采纳。
