ratio

Compared meaning: a comparison between quantities (noun).

比较义项：两个数量之间的比较关系（名词）。

• ratio 本词

  Ratio directly compares two distinct quantities or groups, often expressed as 'x to y' or with a colon; it does not describe a part of a single whole.

  ratio直接比较两个不同的数量或群体，常表示为“x比y”或用冒号连接；它不用于描述整体中的某一部分。

  The ratio of male to female students in the club is about three to one.

  这个社团里男生和女生的比例大约是三比一。

• proportion

  Proportion describes what share or fraction a part makes up of a whole, typically paired with 'large/small' and phrases like 'of the population'.

  proportion表示某一部分占整体的份额或比例，通常与“large/small”连用，并常出现在“……占……的比例”这样的表达中。

  Only a small proportion of the population owns a car in that country.

  那个国家只有一小部分人拥有汽车。

Ratio and proportion both describe comparing amounts. Ratio compares two separate quantities directly, often written as 'x to y', not a part of one whole. Proportion describes what share a part is of a whole, is more formal, and often pairs with 'large' or 'small'.

这两个词都表示数量之间的比较关系，容易混淆：ratio强调两个具体数量之间的比值，常写成“x比y”；proportion强调某一部分占整体的份额，语气更正式，常与large/small等词搭配。
