Question

如果甲數(shù)的絕對(duì)值比乙數(shù)的絕對(duì)值大，那么（　�。�

A．甲數(shù)比乙數(shù)大

B．乙數(shù)比甲數(shù)大

C．甲乙兩數(shù)相等

D．甲乙兩數(shù)不相等

Answer 1

分析：由甲數(shù)的絕對(duì)值比乙數(shù)的絕對(duì)值大，得出甲數(shù)的絕對(duì)值與乙數(shù)的絕對(duì)值不相等，所以甲乙兩數(shù)既不相等也不互為相反數(shù)，由此判斷選擇項(xiàng)．

解答：解：∵甲數(shù)的絕對(duì)值比乙數(shù)的絕對(duì)值大，
∴甲數(shù)的絕對(duì)值與乙數(shù)的絕對(duì)值不相等，
∴甲乙兩數(shù)既不相等也不互為相反數(shù)．
故選D．

點(diǎn)評(píng)：本題考查了絕對(duì)值的定義與性質(zhì)，數(shù)軸上某個(gè)數(shù)與原點(diǎn)的距離叫做這個(gè)數(shù)的絕對(duì)值．如果兩個(gè)數(shù)絕對(duì)值相等，那么這兩個(gè)數(shù)相等或者互為相反數(shù)．
