For a different pizza dough recipe, the equation f=2.5w represents the number of cups of flour, f, that you need for w cups of water. what is the constant of proportionality? explain what it means in this context.

For any direct variation, the equation is of the form y = kx, where k is the constant of proportionality.

Given the equation: f = 2.5w

The constant of proportionality is 2.5.

This means that the ration of the cups of flour to the cups of water used in the recipe is 2.5
