將下列各數(shù)填在相應的集合里.
-3.8,-10,4.3,-|-數(shù)學公式|,-4,0,-(-數(shù)學公式
整數(shù)集合:{         },分數(shù)集合:{          },
正數(shù)集合:{         },負數(shù)集合:{           }.

解:在-3.8,-10,4.3,-|-|,-4,0,-(-)中,
整數(shù)集合:{-10,-4,0 },
分數(shù)集合:{-3.8,4.3,-|-|,-(-)},
正數(shù)集合:{4.3,-(-)},
負數(shù)集合:{-3.8,-10,-|-|,-4}.
分析:首先區(qū)分整數(shù)、分數(shù)、正有理數(shù)、負有理數(shù)的定義,再根據定義選出即可.
點評:本題考查了對有理數(shù)、正數(shù)、負數(shù)等知識點的理解和運用,有理數(shù)由正有理數(shù)、負有理數(shù)和0;整數(shù)和分數(shù)統(tǒng)稱有理數(shù).
