Answer 1

The Solution:

Given:

1/2 stick of butter for every 2 cups of flour.

Required:

To find the number of cups of flour if 3 sticks of butter is used.

Let the number of cups of flour be represented with x.

$\frac{(\frac{1}{2})}{3}=\frac{2}{x}$

Solving for x, we get:

$\begin{gathered} \frac{1}{2}x=2\times3 \\ \\ \frac{1}{2}x=6 \\ \end{gathered}$

Cross multiplying, we get:

$\begin{gathered} x=2\times6=12\text{ } \\ x=12\text{ cups of flour.} \end{gathered}$

Therefore, the correct answer is 12 cups of flour.
