女儿做的算术题

女儿:Daddy, I don't understand this question. Can you help me?
爸爸:OK

Question: "There are 16 stamps on 2 pages. One page has 6 more stamps than the other page. How many stamps are on each page?

爸爸:If we reserve the 6 extra stamps, and the rest of the stamps split equally on both pages, how many stamps will be on each page?

女儿:16
爸爸:Well, you need to have 32 stamps to put 16 on each page. But we only have 16.
女儿:Oops, 8
爸爸:Right. But, if you used them up, where would the 6 extra stamps come from then?
女儿:I got it. 5 and 11

    • 这道题涉及的数学概念应该是一一对应,即多出来的部分是没有与之对应的部分,那么可以一一对应的是5和5。所以一个是5,另一个是5+6。

    • 嘿,不带这么灌水的。
    • 你都说保留了6个,把剩余的平分。她说8个每页,你还说right。真是大白呼。哈哈。
      • 哈哈哈
