男生 48 人, 女生 72 人, 現把男女生各分為若干隊, 每隊人數要相同, 問每隊最多有幾人? 共可分成幾隊?
更新1:
多謝兩位! 兩位的答案, 就是我所不明白的地方!!!! 我自己跟小朋友計算, 答案係: 可分成 24 隊, 每隊 5人. 但老師話錯, 答案係掉換, 即可分成 5 隊, 每隊 24 人. 但我真係唔明老師的答案如何解釋!

題目是: (現把男女生 各分 為若干隊)字面上是: 男生及女生各自組隊 而 不是 男女混合組隊

The H.C.F of 48 and 72 is 24
Therefore there are 24 teams,
Each team contains 48/24=2 boys and 72/24=3 girls
=> 5 people
Therefore:
每隊最多有5人
共可分成24隊

Yes, the answer can be 每隊最多有24人, 共可分成5隊This is a tricky question. Look at the question again: 每隊人數要相同, we only need to consider the same number of people is every team, we do not need to consider the same number of boys and girls at all

So therefore as long as each team as the same number of people, then it is rightsince 24 is the HCF of 24 and 72, the reminders are 3 and 2 =>5so each team has 24 people, there are 5 teams
Therefore there are 24 teams,
Each team contains 48/24=2 boys and 72/24=3 girls
