根据题目,简便的计算方法可以这样算。
1/2-0.16+1/3-0.24+1/6-0.6+1/12
=1/12+(3/6+2/6+1/6)-(0.16+0.24+0.6)
=1/12+1-1
=1/12
1/2-0.16+1/3-0.24+1/6-0.6+1/12
=(1/2+1/3+1/6+1/12)-(0.16+0.24+0.6)
=(6/12+4/12+2/12+1/12)-(0.4+0.6)
=13/12+1
=25/12
简便计算
1/2-0.16+1/3-0.24+1/6-0.6+1/12
=(1/2+1/3+1/6+1/12)-(0.16+0.24+0.6)
=(6/12+4/12+2/12+1/12)-1
=13/12-1
=1/12
答:分数通分,其余的分一类,最后结果相加
1/2-0.16+1/3-0.24+1/6-0.6+1/12
=(1/2+1/3+1/6+1/12)-(0.16+0.24+0.6)
=(3/6+2/6+1/6+1/12)-1
=1+1/12-1
=1/12
