In order to determine which pair of ratios form a true proportion, we need to check if the cross products are equal.
For example, let's consider the pair of ratios:
$\frac{2}{3}$ and $\frac{4}{6}$
The cross products would be $2 \times 6$ and $3 \times 4$, which are equal to 12. Therefore, this pair of ratios forms a true proportion.
Another example:
$\frac{3}{4}$ and $\frac{5}{8}$
The cross products would be $3 \times 8$ and $4 \times 5$, which are not equal (they are 24 and 20, respectively). Therefore, this pair of ratios does not form a true proportion.
Therefore, the pair of ratios that form a true proportion is $\frac{2}{3}$ and $\frac{4}{6}$.
