Answer:
The constant of proportionality for a ratio is determined by dividing one part of the ratio by the other. In the case of the ratio 3 to 4, the constant of proportionality (k) can be found by dividing 4 by 3:
\[ k = \frac{4}{3} \]
So, the constant of proportionality for the ratio 3 to 4 is \(\frac{4}{3}\).
