Question

two thirds of the floats in the parade have flowers, what is the constant of proportionality

Answer 1

Let x represent the number of floats in the parade and y represent the number of floats that have flowers.

If y varies directly with x, you can determine the number of floats that have flowers as:

$y=\frac{2}{3}x$

The constant of proportionality is then

$k=\frac{2}{3}$
