分析:正數(shù)就是大于0的數(shù);負數(shù)就是在正數(shù)前加上負號;整數(shù)就是像-2,-1,0,1,2這樣的數(shù);正分數(shù)就是在有理數(shù)的集合中,大于0的分數(shù);小于0的分數(shù)即為負分數(shù),根據(jù)這些數(shù)的特點,得出相應的數(shù).
解答:∵正數(shù)就是大于0的數(shù),
∴正數(shù)有3,+3.333,+8,+
,
∵負數(shù)就是在正數(shù)前加上負號,
∴負數(shù)有-0.01,-
,-0.010010001…,-100,-101.1,
∵整數(shù)就是像-2,-1,0,1,2這樣的數(shù),
∴整數(shù)有:3,0,+8,-100,
∵正分數(shù)就是在有理數(shù)的集合中,大于0的分數(shù),也可以是能化為分數(shù)的正小數(shù),
∴正分數(shù)有+3.333,+
,
∵負分數(shù)就是小于0的分數(shù),也可以是能化為分數(shù)的負小數(shù),
∴負分數(shù)有-0.01,-101.1,
故答案為(3,+3.333,+8,+
),(-0.01,-
,-0.010010001…,-100,-101.1),(3,0,+8,-100),(+3.333,+
),(-0.01,-101.1).
點評:本題考查了正數(shù),負數(shù),整數(shù),正分數(shù),負分數(shù)的定義,難度不大.
