Question

寫出下列各數(shù)的絕對(duì)值：-1.5，6.2，，0，39，，-47．

Answer 1

解：-1.5的絕對(duì)值是1.5，
6.2的絕對(duì)值是6.2，
的絕對(duì)值是，
0的絕對(duì)值是0，
39的絕對(duì)值是39，
2的絕對(duì)值是2，
-47的絕對(duì)值是47．
分析：根據(jù)絕對(duì)值的性質(zhì)分別計(jì)算即可得解．
點(diǎn)評(píng)：本題考查了絕對(duì)值的性質(zhì)，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．
