把下列各數(shù)填在相應(yīng)的集合內(nèi):
-7,3.5,-3.14,0,
17
13
,0.03%,-3
1

,10.
正數(shù)集合:{
3.5,
17

,0.03%,10
3.5,
17
13
,0.03%,10
};
負(fù)數(shù)集合:{
-7,-3.14,-3

};
正分?jǐn)?shù)集合:{

,0.03%
};
非負(fù)整數(shù)集合:{
3.5,0,
17
13
,0.03%,10
3.5,0,
17
13
,0.03%,10
}.
分析:根據(jù)有理數(shù)的分類(lèi)進(jìn)行判斷即可.有理數(shù)包括:整數(shù)(正整數(shù)、0和負(fù)整數(shù))和分?jǐn)?shù)(正分?jǐn)?shù)和負(fù)分?jǐn)?shù)).
解答:解:正數(shù)集合:{ 3.5,
17
13
,0.03%,10};
負(fù)數(shù)集合:{-7,-3.14,-3

,0.03%};
非負(fù)整數(shù)集合:{ 3.5,0,

,0.03%,10.
點(diǎn)評(píng):本題考查了有理數(shù)的分類(lèi),認(rèn)真掌握正數(shù)、負(fù)數(shù)、整數(shù)、分?jǐn)?shù)、正有理數(shù)、負(fù)有理數(shù)、非負(fù)數(shù)的定義與特點(diǎn).注意整數(shù)和正數(shù)的區(qū)別,注意0是整數(shù),但不是正數(shù).
