3/4×2/5+3/4×0.6简便算法是先提出3/4得到3/4×(2/5+0.6),把0.6改写成分数3/5变成3/4×(2/5+3/5)=3/4×1=3/4。
计算这道题时,要先将小数0.6化成分数3/5,然后提取相同因数再计算,3/4 X2/5十3/4X0.6=3/4x2/5十3/4X3/5=3/4X(2/5十3/5)=3/4X1=3/4
3/4*2/5+3/4*0.6
=3/4*(2/5+0.6)
=3/4*(0.4+0.6)
=3/4*1
=3/4
=3/4×2/5+3/4×3/5
=3/4×(2/5+3/5)
=3/4×1
=3/4
3/4x2/5+3/4x0.6
=3/4×(0.4+0.6)
=3/4x1
=3/4
