题目内容
【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:<,>,=.
