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.
