To describe the relationship between the number of buses and the number of students, we can set up a proportion based on the information provided.
From the first statement: 2 buses can transport 75 students. This gives us the ratio of buses to students as:
\[ \frac{2 \text{ buses}}{75 \text{ students}} \]
From the second statement: 8 buses can transport 300 students. This provides us with another ratio:
\[ \frac{8 \text{ buses}}{300 \text{ students}} \]
Thus, the two ratios that describe the relationship between the number of buses and the number of students are:
\[ \frac{2 \text{ buses}}{75 \text{ students}} \quad \text{and} \quad \frac{8 \text{ buses}}{300 \text{ students}} \]
These ratios represent the relationship without reducing them to their lowest terms.
