Answer

Explanation:

Step1: Find the ratio of parents to students

The ratio of parents to students on the aquarium field - trip is $\frac{15}{75}=\frac{1}{5}$.

Step2: Calculate the number of parents for 25 students

Let the number of parents be $x$. Since the ratio is $\frac{1}{5}$, we have $\frac{x}{25}=\frac{1}{5}$. Cross - multiply gives $5x = 25$. Then $x=\frac{25}{5}=5$.
