Q. Part D

\newline

Write an equation, using

f

and

w

, to represent how the number of cups of flour is proportional to the number of cups of water.

\newline

Answer

\qquad

Identify relationship: Identify the relationship between flour and water. Since they are proportional, the equation will be of the form $f = kw$ , where $k$ is the constant of proportionality.
Determine value of k: Determine the value of $k$ . Assume for simplicity that the recipe requires $1$ cup of flour for every $2$ cups of water. So, $k = \frac{1}{2}$ .
Write equation with $k$ : Write the equation using the value of $k$ . $f = \frac{1}{2}w$ .
