Decimals, Fractions, Percentages, and Multiples in Chinese

小数、分数、百分数和倍数 xiǎoshù, fēnshù, bǎifēnshù hé bèishù

Mandarin reads a decimal with 点 followed by individual digits, a fraction with the denominator before 分之 and the numerator after it, and a percentage with 百分之 before the number. Multiples place a numeral before 倍. These forms encode mathematical values; their comparison syntax may require additional markers such as 是 or 的.

Read the structure

Mandarin reads a decimal with 点 followed by individual digits, a fraction with the denominator before 分之 and the numerator after it, and a percentage with 百分之 before the number. Multiples place a numeral before 倍. These forms encode mathematical values; their comparison syntax may require additional markers such as 是 or 的. Keep the model Whole + 点 + Digits; Denominator + 分之 + Numerator; 百分之 + Number; Number + 倍 visible while you compare each sentence.

三点二五是一个小数。

3.25 is a decimal.

Choose the right context

Read decimal digits individually after 点. Put the denominator before 分之 and the numerator after it. Express percentages with 百分之 and multiplicative values with number plus 倍.

三分之二的学生来了。

Two thirds of the students came.

Respect the boundary

Do not read the decimal tail as one multi-digit integer. Do not put the numerator before 分之 in the standard fraction form. Do not use 倍 alone when the multiplier must be specified.

三点二十五是一个小数。

(Three point twenty-five is a decimal.)

Repair the pattern

The decimal tail is read as an integer: Digits after decimal 点 are read one by one, so .25 is 二五 rather than 二十五. The fraction order is reversed: For two thirds, denominator 三 precedes 分之 and numerator 二 follows it.

三点二五是一个小数。

Use the repaired structure without changing the intended meaning.

02 / MAP

Read the Sentence

Read from left to right and notice the job performed by each part. The labels describe this example; they are not a rule that every Chinese sentence must copy.

This part occupies the 点 position in the model pattern.

Digits; Denominator

This part occupies the Digits; Denominator position in the model pattern.

分之

This part occupies the 分之 position in the model pattern.

Numerator; 百分之

This part occupies the Numerator; 百分之 position in the model pattern.

一个

Number; Number

This part occupies the Number; Number position in the model pattern.

This part occupies the 倍 position in the model pattern.

03 / EXAMPLES

Examples You Can Reuse

Keep the structure stable while changing the people, objects, times, or conditions. Pinyin is shown as reading support; use the Chinese sentence and translation to confirm the grammar relationship.

三点二五是一个小数。

Sān diǎn èr wǔ shì yí ge xiǎoshù.

3.25 is a decimal.

三分之二的学生来了。

Sān fēn zhī èr de xuéshēng lái le.

Two thirds of the students came.

今年的产量是去年的两倍。

Jīnnián de chǎnliàng shì qùnián de liǎng bèi.

This year's output is twice last year's.

04 / LIMITS

When to Use It — and When Not To

Use it when

  • Read decimal digits individually after 点.
  • Put the denominator before 分之 and the numerator after it.
  • Express percentages with 百分之 and multiplicative values with number plus 倍.

Do not use it when

  • Do not read the decimal tail as one multi-digit integer.
  • Do not put the numerator before 分之 in the standard fraction form.
  • Do not use 倍 alone when the multiplier must be specified.

05 / REPAIR

Compare Right and Wrong

Compare the smallest meaningful change. Each explanation identifies a placement, scope, form, or clause relationship instead of treating the whole sentence as one undifferentiated mistake.

三点二十五是一个小数。

三点二五是一个小数。

The decimal tail is read as an integer

Digits after decimal 点 are read one by one, so .25 is 二五 rather than 二十五.

二分之三的学生来了。

三分之二的学生来了。

The fraction order is reversed

For two thirds, denominator 三 precedes 分之 and numerator 二 follows it.

三点二十五是一个小数。

Sān diǎn èrshíwǔ shì yí ge xiǎoshù.

Digits after decimal 点 are read one by one, so .25 is 二五 rather than 二十五.

二分之三的学生来了。

Èr fēn zhī sān de xuéshēng lái le.

For two thirds, denominator 三 precedes 分之 and numerator 二 follows it.

06 / PRACTICE

Practice the Grammar Point

Complete three short tasks in order: judge the pattern, repair a common error, and build the sentence. Feedback is fixed and reviewed, so these activities do not use a checker allowance.

1. Judge the sentence

Question 11/1
Which sentence uses 小数、分数、百分数和倍数 correctly?

2. Choose the correction

Question 11/1
Choose the correction that fixes: 二分之三的学生来了。

3. Build the sentence

Build a complete sentence with 小数、分数、百分数和倍数.

07 / APPLY

Apply It in Your Sentence

Write one original sentence with 小数、分数、百分数和倍数. Your draft moves to the checker through this browser session, selects this grammar point as the first review focus, and waits for you to submit.

08 / QUESTIONS

Decimals, Fractions, Percentages, and Multiples Questions

How do I say 20 percent?

Say 百分之二十. 百分之 functions like the fixed hundredths frame before the percentage number.

Does 两倍 mean two times as much or two times more?

In an equation such as A是B的两倍, it means A equals two units of B. English 'times more' wording can be ambiguous, so compare the actual values.
