30的英文

Title: 30 in English

In the English language, the number "30" is written as "thirty." It is a combination of the word "three" and the suffix "ty," which is used to form the tens place in numbers from ten to ninety. The number 30 represents a quantity that is three times ten, and it is commonly used in various contexts such as counting, measurements, and time.

For example:

I am thirty years old. (I am 30 years old.)

She has thirty dollars in her wallet. (She has $30 in her wallet.)

The movie will start in thirty minutes. (The movie will start in 30 minutes.)

The word "thirty" is also used in compound numbers when referring to amounts or quantities that are larger than 30 but less than 100. For example:

Fortythree (43)

Fiftyseven (57)

In English, when writing numbers, it is important to note that "thirty" is a single word and should not be separated into "three" and "ty."
