Question

絕對(duì)值小于5.3的負(fù)整數(shù)是________，整數(shù)有________個(gè)．

Answer 1

-1，-2，-3，-4，-5    11
分析：當(dāng)一個(gè)數(shù)為非負(fù)數(shù)時(shí)，它的絕對(duì)值是它本身；當(dāng)這個(gè)數(shù)是負(fù)數(shù)時(shí)，它的絕對(duì)值是它的相反數(shù)．
解答：絕對(duì)值小于5.3的整數(shù)有0，±1，±2，±3，±4，±5．
∴絕對(duì)值小于5.3的負(fù)整數(shù)是-1，-2，-3，-4，-5；整數(shù)有11個(gè)．
故答案為：-1，-2，-3，-4，-5；11．
點(diǎn)評(píng)：此題比較簡(jiǎn)單，熟悉絕對(duì)值的定義，根據(jù)題意即可得到答案．
