题目

Pam and Stanley packed several boxes with reams of paper. While both packed, Pam packed 60% of the boxes. After Pam stopped, Stanley packed the same number of boxes that he had packed while working with Pam. What is the ratio of the number of boxes Pam packed to the number of boxes Stanley packed?

选项

1 to 4

1 to 3

3 to 5

3 to 4

3 to 2

解析

我们可以通过代入满足条件的数值来解这道题。帕姆和斯坦利打包了若干箱纸。两人一起打包时，帕姆打包了总箱数的60%。假设这段时间里，两人一共打包了10箱。由于帕姆打包了60%，因此帕姆打包了6箱，斯坦利打包了剩余的4箱。帕姆停止工作后，斯坦利又打包了和两人合作时相同数量的箱子。这意味着斯坦利在帕姆离开后又打包了4箱。因此，斯坦利打包的总箱数 = \(4 + 4 = 8\) 箱。问题：帕姆打包的箱数与斯坦利打包的箱数之比是多少？帕姆打包了6箱斯坦利打包了8箱比例为 6:8 化简后得到 3:4 答案：D
