給下列有理數(shù)分類(用逗號隔開分)
101,-9.25,-︳-7 ︳,-3,-(-2),31.25,-(+3.5),0,
整數(shù) {________};
負分數(shù) {________};
非負數(shù) {________};
負整數(shù) {________}.
101,-|-7|,-3,-(-2),0,… -9.25,-(+3.5),… 101,-(-2),31.25,0,… -|-7|,-3,••
分析:先區(qū)分整數(shù)、負分數(shù)、非負數(shù)、負整數(shù)的含義,再根據(jù)意義選出即可.
解答:整數(shù){101,-|-7|,-3,-(-2),0,…},
負分數(shù){-9.25,-(+3.5),…},
非負數(shù){101,-(-2),31.25,0,…},
負整數(shù){-|-7|,-3,…},
故答案為:101,-|-7|,-3,-(-2),0,-9.25,-(+3.5),101,-(-2),0,-|-7|,-3.
點評:本題考查了對有理數(shù)、整數(shù)、負分數(shù)、非負數(shù)、負整數(shù)的含義的理解和運用,注意:整數(shù)包括正整數(shù)、0、負整數(shù);非負數(shù)包括正數(shù)和0.
