將下列各數(shù)填在相應(yīng)的集合里.
-3.8,-10,4.3,-|-數(shù)學(xué)公式|,42,π,3,101001000…,0,-(-數(shù)學(xué)公式
整數(shù)集合:{                …};
分?jǐn)?shù)集合:{                …};
正數(shù)集合:{                …};
負(fù)數(shù)集合; {                …};
有理數(shù)集合:{                …}.

解:-|-|=,42=16,-(-)=
則整數(shù)集合:{-10,42,3,0…};
分?jǐn)?shù)集合:{4.3,-|-|,-(-)…};
正數(shù)集合:{4.3,42,π,3,101001000…,-(-)…};
負(fù)數(shù)集合:{-3.8,-10,-|-|,…},
有理數(shù)集合:{-3.8,-10,4.3,-|-|,42,3,0,-(-)}.
故答案是::-10,42,3,0;4.3,-|-|,-(-);4.3,42,π,3,101001000…,-(-);-3.8,-10,-|-|;-3.8,-10,4.3,-|-|,42,3,0,-(-).
分析:先對(duì)于第四、五、十個(gè)式子化簡(jiǎn),利用各自的定義判斷,即可得到正確結(jié)果.
點(diǎn)評(píng):考查了有理數(shù),認(rèn)真掌握有理數(shù)的分類;注意整數(shù)、0、正數(shù)之間的區(qū)別:0是整數(shù)但不是正數(shù).
