Answer:

Every ratio y/x for related pairs of x and y is equivalent;

[tex]\text{Every ratio }\frac{y}{x}\text{ for related pairs of x and y is equivalent.}[/tex]

Explanation:

Given that x and y are proportional;

[tex]\begin{gathered} y\propto x \\ y=kx \\ \frac{y}{x}=k \end{gathered}[/tex]

where k is the constant of proportionality;

If x and y are proportional then the ratio of y/x is constant for all related pairs.

Therefore, Every ratio y/x for related pairs of x and y is equivalent;

[tex]\text{Every ratio }\frac{y}{x}\text{ for related pairs of x and y is equivalent.}[/tex]
