9.6×3.6+7.2×0.2的简便算法
问题描述：
9.6×3.6+7.2×0.2的简便算法
答
9.6*3.6+2*3.6*0.2=9.6*3.6+0.4*3.6=3.6
答
9.6*3.6+7.2*0.2=9.6*3.6+3.6*2*0.2=(9.6+0.2*2)*3.6=10*3.6=36
答
9.6×3.6+7.2×0.2
=9.6×3.6+2×3.6×0.2
=9.6×3.6+3.6×0.4
=36
把7.2分解成2和3.6相乘,把2和0.2相乘,就出来了.
祝你学业有成
答
(10-0.4)*3.6+(7+0.2)*0.2=36
上面的更好
答
9.6×3.6+7.2×0.2
=9.6×3.6+3.6×0.4
=3.6×(9.6+0.4)
=3.6×10
=36
