考點(diǎn):有理數(shù)大小比較
專題:
分析:(1)根據(jù)正數(shù)大于負(fù)數(shù),可得答案;
(2)根據(jù)分?jǐn)?shù)的分子相同分母越小分?jǐn)?shù)越大,可得答案;
(3)根據(jù)零大于負(fù)數(shù),可得答案;
(4)根據(jù)兩負(fù)數(shù)比較大小,絕對(duì)值大的反而小,可得答案;
(5)根據(jù)互為相反數(shù)的兩個(gè)數(shù)的絕對(duì)值相等,可得答案;
(6)根據(jù)正數(shù)大于負(fù)數(shù),可得答案;
(7)根據(jù)正數(shù)大于負(fù)數(shù),可得答案;
(8)根據(jù)絕對(duì)值的意義,可得答案.
解答:解:(1)-3<3
(2)
<
(3)0>-10
(4)-3.14>-π
(5)|
-|=|
|
(6)|-3.5|>-3.5
(7)|0|<|-0.58|
(8)|-5.9|<|-6.2|
故答案為:<,<,>,>,=,>,<,<.
點(diǎn)評(píng):本題考查了有理數(shù)比較大小,利用了正數(shù)大于零,零大于負(fù)數(shù).
