Expressing Ratios/Multiples

To express multiples in Chinese, use Number + 倍. 一倍 means "one fold" (the original amount), so 两倍 means "two times" and 三倍 means "three times." When saying something increased to a multiple, use 是...的 + Number + 倍 or 增加了 + Number + 倍. Be careful: 增加了一倍 means "increased by one fold" (doubled), not increased by the original amount.

For fractions, Chinese uses the format: Denominator + 分之 + Numerator. This reads from large to small, opposite to English. For example, 三分之一 means "one-third" (literally: "of three parts, one"). Percentages follow the same logic: 百分之 + Number. 百分之五十 = 50%. 千分之 is used for per mille.

These expressions are essential for academic, business, and everyday contexts. They appear in news reports, statistics, scientific papers, and daily conversation about prices, grades, and proportions. Mastering them is crucial for discussing data and quantitative information in Chinese.
