Incredibly obvious answer isn't obvious?

Question

Somebody asked me why this was wrong, and I can't think of an answer.

It's basically asking you to create an expression for a number divided by 3.

So would this not be n/3? If you look in the picture, the answer is marked wrong.

Is this a glitch on the webpage or am I missing something obvious?

This is definetely a glitch on the web site - your answer is most definetely correct. :) — Mufasa, Sep 03 '13 at 22:22

"A number divided by $3$" is indeed $n\div 3$.

(Alternatively the same is represented by $\dfrac n3$, but since $\dfrac n3$ isn't in the list of options go with the also-correct $n\div 3$.)
