Question

-0.2的倒數(shù)是________，絕對(duì)值是________．

Answer 1

-5    0.2
分析：根據(jù)倒數(shù)的性質(zhì)，互為倒數(shù)的兩個(gè)數(shù)積為1；絕對(duì)值的定義，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，求解即可．
解答：根據(jù)倒數(shù)和絕對(duì)值的定義得：
-0.2的倒數(shù)為：1÷（-0.2）=-5，
-0.2的絕對(duì)值為：0.2．
故答案為：-5，0.2．
點(diǎn)評(píng)：本題主要考查了絕對(duì)值、倒數(shù)的定義．a(chǎn)的倒數(shù)是 ；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，難度適中．
