The Vietnamese word "phân số" translates to "fraction" in English. It is a mathematical term used to represent a part of a whole or, in other words, a number that expresses a relationship between two quantities.

Basic Definition:

• Phân số (noun): This refers to a number that is written as one integer over another, separated by a line. For example, in the fraction 1/2, "1" is the numerator (the top number), and "2" is the denominator (the bottom number). This means that 1 out of 2 equal parts is being considered.

Usage Instructions:

• You use "phân số" when discussing mathematics, especially in contexts where you are dealing with parts of a whole, ratios, or proportions.
• To create a fraction in Vietnamese, you can say "phân số" followed by the numerator and denominator. For example: "phân số 3/4" means "the fraction three-fourths."

Example:

• Simple Example: "Một phần ba là một phân số." (One third is a fraction.)
• Mathematical Example: "Khi bạn chia bánh thành 4 phần, mỗi phần là một phân số, ví dụ như 1/4." (When you divide a cake into 4 parts, each part is a fraction, for example, 1/4.)

Advanced Usage:

• In more advanced mathematics, "phân số" can also refer to improper fractions (where the numerator is larger than the denominator) and mixed numbers (which combine a whole number and a fraction).
• Example: "Phân số 5/3 là một phân số không đúng." (The fraction 5/3 is an improper fraction.)

Word Variants:

• "Phân số thập phân": Decimal fraction (e.g., 0.5)
• "Phân số hỗn hợp": Mixed fraction (e.g., 1 1/2)

Different Meanings:

While "phân số" primarily refers to a mathematical fraction, in a broader context, "phân" can mean "to divide" or "to separate," and "số" means "number." Thus, "phân số" literally suggests "divided number."

Synonyms:

• "Tỷ lệ" (ratio): While not exactly the same, it relates to comparing two quantities and can sometimes be used interchangeably in certain contexts.
• "Phân số nguyên" (whole fraction): Another term sometimes used for whole numbers, but this is less common.
