#### Answer

Ans: 3299 students out of total 8247 students are expected to vote.

#### Work Step by Step

Let's assume the x is the number of students expected to vote.
Now, we will write the proportion for the given details
$\frac{4 }{10} = \frac{x}{8247}$
so. $ 4\times 8247= x\times 10$ (cross multiply)
Now divide both sides by 10.
$\frac{32988}{10} = \frac{10 x}{10}$
$ x = 3298.8 \approx 3299$
3299 students out of total 8247 students are expected to vote.
