Answer :
Let's compare the percentages of correct answers for each friend:
1. For Aries, the percentage is given as:
$$85\%.$$
2. For Quan, he got 18 out of 20 questions correct. To find his percentage:
$$\frac{18}{20} \times 100\% = 90\%.$$
3. For Ty, he got $\frac{4}{5}$ of the questions correct, which is:
$$\frac{4}{5} \times 100\% = 80\%.$$
4. For Prince, he got $\frac{3}{4}$ of the questions correct, which is:
$$\frac{3}{4} \times 100\% = 75\%.$$
Now, comparing the percentages:
$$\text{Aries: } 85\%, \quad \text{Quan: } 90\%, \quad \text{Ty: } 80\%, \quad \text{Prince: } 75\%.$$
The highest percentage is $90\%$, which belongs to Quan.
Thus, the student with the highest percentage of questions correct on the test is Quan.
