Question

Sydney buys a fish tank and some guppies. for every 5 guppies, the tank needs 4 gal of water. Wich statement about the relationship between the gallons of water and the number of guppies

Answer 1

Since we have that for every 5 guppies, the tank needs 4 gals of water, we have the following proportionality:

$\begin{gathered} 5\colon4\text{ } \\ or \\ \frac{5}{4} \end{gathered}$

Therefore, 5/4 is the constant of proportionality needed
