Question

Jonshelle is developing a new bread recipe. The relationship between cups of water, w, and cups of flour, f, is w = 7/10f. What is the scale factor of water to flour?

Answer 1

Answer:

The scale factor of water to flour represents the proportionality ratio, that is, $k = \frac{7}{10}$.

Step-by-step explanation:

According to the statement, we know that it exists a linear relationship between cups of water ($w$) and cups of flour ($f$). That is:

$w = k\cdot f$ (Eq. 1)

Where $k$ is the proportionality ratio, measured in cups of water per cup of flour.

Therefore, the scale factor of water to flour represents the proportionality ratio, that is, $k = \frac{7}{10}$.
