Answer:

[tex]3 < n[/tex]

Step-by-step explanation:

We have the phrase "Three less than a number"

Three would be the number 3.

The phrase "less than" indicates a less than sign.

"A number" is unknown, so said number would be n. Of course, you can use any letter as your variable.

Three less than a number should be [tex]3 < n[/tex].
