【题目】在横线里填上“>”、“<”或“=”.

200﹣5.24﹣24.76   200+(5.24+24.76)

(6.3+2.7)+9.5   5.9+(6.3+2.7)

23.17+3.56+45.83   23.17+45.83+3.56.

【答案】<,>,=

【解析】

试题分析:根据小数加减法的混合运算的方法,把算式的结果求出来,然后再根据小数大小比较的方法进行解答.

解:

(1)200﹣5.24﹣24.76,

=200﹣(5.24+24.76),

=200﹣30,

=170;

200+(5.24+24.76),

=200+30,

=230;

170<230;

所以,200﹣5.24﹣24.76<200+(5.24+24.76);

(2)(6.3+2.7)+9.5,

=9+9.5,

=18.5;

5.9+(6.3+2.7),

=5.9+9,

=14.9;

18.5>14.9;

所以,(6.3+2.7)+9.5>5.9+(6.3+2.7);

(3)23.17+3.56+45.83,

=23.17+45.83+3.56

=69+3.56,

=72.56;

23.17+45.83+3.56

=69+3.56,

=72.56;

所以,23.17+3.56+45.83=23.17+45.83+3.56.

故答案为:<,>,=.
