To write the phrase "half of n" as an expression, we need to consider what "half" of a value represents.
1. "Half" means dividing by 2.
2. "n" is the variable we are working with.
So, "half of n" can be translated mathematically as:
[tex]\[
\frac{n}{2}
\][/tex]
Let's compare this with the given options:
- Option A: [tex]\( n^2 \)[/tex] - This represents "n squared," not half of n.
- Option B: [tex]\(\frac{n}{2}\)[/tex] - This correctly represents "half of n."
- Option C: [tex]\(2n\)[/tex] - This represents "twice n," not half of n.
- Option D: [tex]\(\frac{1}{n}\)[/tex] - This represents "the reciprocal of n," not half of n.
The correct expression that stands for "half of n" is:
[tex]\[
\boxed{\frac{n}{2}}
\][/tex]
