Question

數(shù)軸上原點(diǎn)表示的數(shù)是______，絕對(duì)值最小的有理數(shù)是_______.

 

Answer 1

【答案】

0，0

【解析】

試題分析：根據(jù)數(shù)軸的知識(shí)、絕對(duì)值的規(guī)律求解即可.

解：數(shù)軸上原點(diǎn)表示的數(shù)是0；絕對(duì)值最小的有理數(shù)是0.

考點(diǎn)：數(shù)軸的知識(shí)，絕對(duì)值的規(guī)律

點(diǎn)評(píng)：解題的關(guān)鍵是熟練掌握絕對(duì)值的規(guī)律：正數(shù)和0的絕對(duì)值是它本身，負(fù)數(shù)的絕對(duì)值是它的相反數(shù).
