Final answer:
The sentence that expresses numbers correctly is: The planning meeting scheduled for November 1st has been postponed.
Step-by-step explanation:
The sentence that expresses numbers correctly is: The planning meeting scheduled for November 1st has been postponed.
In this sentence, the date is expressed using cardinal numbers (1st), which is the correct way to represent the date. In English, ordinal numbers (like 1st, 2nd, 3rd) are used to indicate the position or order of something, while cardinal numbers (like 1, 2, 3) are used to represent actual quantities or dates.
For example, when talking about a specific date, we use cardinal numbers (November 1). On the other hand, when talking about the position of something in a series or list, we use ordinal numbers (1st, 2nd, 3rd, etc.).
