Question

的倒數(shù)是________，絕對(duì)值是________．

Answer 1

-    3
分析：利用絕對(duì)值和倒數(shù)的性質(zhì)分別求出即可得出答案．
解答：-3=-的倒數(shù)是-，絕對(duì)值是3．
故答案為：-，3．
點(diǎn)評(píng)：此題考查了絕對(duì)值和倒數(shù)的性質(zhì)，要求掌握絕對(duì)值和倒數(shù)的性質(zhì)及其定義，并能熟練運(yùn)用到實(shí)際當(dāng)中．絕對(duì)值規(guī)律總結(jié)：一個(gè)正數(shù)的絕對(duì)值是它本身；一個(gè)負(fù)數(shù)的絕對(duì)值是它的相反數(shù)；0的絕對(duì)值是0．倒數(shù)的定義：若兩個(gè)數(shù)的乘積是1，我們就稱這兩個(gè)數(shù)互為倒數(shù)．
