A certain class has 45 students. The math scores after a test follow a normal distribution $N(80, 5^{2})$. The number of students theoretically scoring between 85 and 90 points is approximately _____. (Round to the nearest whole number) <br/>Given: $P(\mu -\sigma \leqslant X \leqslant \mu +\sigma) \approx 0.6827$, $P(\mu -2\sigma \leqslant X \leqslant \mu +2\sigma) \approx 0.9545$, $P(\mu -3\sigma \leqslant X \leqslant \mu +3\sigma) \approx 0.9973$.
