The structure of a proportion is
[tex]\frac{part}{whole} = \frac{part}{whole}[/tex]
The whole of the first fraction is 5. This is because the survey is looking at incriments of 5 students
The part of the first fraction is 2. This is because a fraction (part) of the incriments of 5 students that ride the bike is 2.
The whole of the second fraction is 65. This is because there is a total of 65 students.
The part of this fraction is unknown (n)
So...
first fraction: part = 2 whole = 5
second fraction: part = n whole = 65
The proportion for this question is:
[tex]\frac{2}{5} = \frac{n}{65}[/tex]
Hope this helped!
