简便算法5.6×0.375+0.375×5.4-37.5%简便算法5.6×0.375+0.375×5.4-37.5%简便算法5.6×0.375+0.375×5.4-37.5%5.6×0.375+0.3
简便算法 5.6×0.375+0.375×5.4-37.5%
简便算法 5.6×0.375+0.375×5.4-37.5%
简便算法 5.6×0.375+0.375×5.4-37.5%
5.6×0.375+0.375×5.4-37.5%
=(5.6+5.4-1)×37.5%
=10×37.5%
=3.75
5.6×0.375+0.375×5.4-37.5%
=0.375x(5.6+5.4-1)
=0.375x10
=3.75
5.6×0.375+0.375×5.4-37.5%
=5.6×0.375+0.375×5.4-0.375
=0.375×（5.6+5.4-1）
=0.375×10
=3.75
提出0,375,得0,375x(5,6 5,4-1)
...... 0.375*（5.6+5.4-1）=3.75 如果37.5% 可以认为是0.375的话
