    [詞彙Q&A] Q: percent,percentage ,rate ,ratio ,proportion 有什麼區別?

    A: percent (%)百分之(某數字) 一般都是有數字在前面的時候用 (數字+percent of sb or sth)

    E.g. I only answered 20 percent of the questions correctly. You shouldn't have copied my answers.

    E.g. 85% of Eric’s paycheck goes to his wife. The other 15% goes to the government. Both do nothing for Eric.

    percentage百分率
    通常在 the/a small/a large...+percentage of sb or sth 的時候用

    1. Percentage被放在 the後時,用單數形動詞:
    E.g. The percentage of uneducated people in this city is relatively small. Nearly everyone has a bachelor's degree or above.

    當被放在 a後時,可用動詞單數或複數形式,這由後面所跟的名詞數量而定:

    E.g. A large percentage of children in the school come from single-parent families.

    E.g. A large percentage of the crop has spoiled.
    -------------------------------------------------------
    rate指的是比率,比值,率等,如tax rate稅率,crime rate犯罪率等。

    E.g. The crime rate in this city is rapidly increasing. There are violent crimes happening almost every day.
    -------------------------------------------------------
    ratio指的是兩個量的比值,其實是強調相比、相除的關係,但是它的兩個量必須在上下文出現。比例 (必須有確切的數字)

    E.g. The ratio of students to teachers is 35:1.
    -------------------------------------------------------
    proportion是指比例關係,可代替ratio使用,但是在相比的兩個量在上下文沒有出現是必須用proportion而不能用ratio。

    E.g. Only a tiny proportion of the population is infected by the H7N9 virus.
