We have to write an equation to represent the situation.
We know that 15 oz are 3/5 of the volume of the water, that we will call x.
This can be written as:
[tex]15=\frac{3}{5}x[/tex]We can use it to find x as:
[tex]\begin{gathered} 15=\frac{3}{5}x \\ x=\frac{5}{3}\cdot15 \\ x=25 \end{gathered}[/tex]Answer:
The equation is 15 = 3/5*x.
The value of x is 25 ounces.
