1.25×0.32×2.5 2.5怎么简便计算

2.5×0.32×1.25 = 2.5×1.25×0.4×0.8 =(2.5×0.4)×(1.25×0.8) =1×1 =1

1.25×0.32×2.5+2.5 =1.25x0.8x(0.4x2.5)+2.5 =1x1+2.5 =3.5

能简便的简便 1.25×0.32×2.5 =(1.25×0.8)×(0.4×2.5) =1×1 =1

0.32拆成0.4×0.8 2.5×0.4=1 1.25×0.8=1 所以结果是1

解: 1.25x2.5x0.32 =(1.25*0.8)(2.5*0.4) =1*1 =1

(1)2.5×32×1.25 =(2.5×4)×(8×1.25),=10×10,=100;(2)(512+56-38)÷124=(512+56-38)×24,=512×24+56×24-38×24,=10+20-9,=21;(3)719×67+1319÷76-67=719×67+1319×67-67,=(719+1319-1)×67,=119×67,=6133.

=3.62+3.62*0.01=3.62+0.0362=3.652

=1.25×0.8×0.4×2.5+2.5 =1×1+2.5 =3.5

=0.04×8×2.5×1.25 =0.04×2.5×8×1.25 =0.1×10 =1

解: 1.25✘0.32✘0.25 =1.25*0.08*4*0.25 =0.1*(4*0.25) =0.1
