3.5十0.5x0.25怎么简便 -
3.5+0.5x0.25 =3.5x0.125 =3.625
(5.3-0.5)×0.25 =4.8×0.25 =1.2×（4×0.25）1.2×1 =1.2
3.5+0.5x0.25 =3.5x0.125 =3.625
(5.3-0.5)×0.25 =4.8×0.25 =1.2×（4×0.25）1.2×1 =1.2
2.4×0.5×0.25 ＝2.4×1/2×1/4 ＝2.4×1/8 ＝0.3
2.5÷（0.5×0.25）2.5÷2.5÷0.25 =1÷0.25 =4
0.5x0.25x0.2x40简便方法怎么算? -
0.5×0.25×0.2×40 ＝（0.5×0.2）×（0.25×40）＝0.1×10 ＝1
解：依题意得算式，0.25×5.6×0.5 =0.25×（4×2×0.7）×0.5 =0.25×4×2×0.7×0.5 =1×0.7×（2×0.5）0.7×1 =0.7 即0.25×5.6×0.5=0.7
0.5x等于0.25。解方程? -
0.5x=0.25 解：x=0.25÷0.5 x=0.5

0.5+0.25x=2 -
解：0.25x=2-0.5 x=1.5÷0.25 x=6
1.25x64x0.5x0.25=(1.25x8)x(2x0.5)x(4x0.25)=10x1x1=10
