Answer
Explanation:
Step1: Calculate the Recipe Conversion Factor (RCF)
The formula for RCF is $\frac{\text{New Yield}}{\text{Old Yield}}$. Here, the new yield is for 6 people and the old yield is 12 servings. So, $RCF=\frac{6}{12}= 0.5$.
Step2: Calculate new ingredient amounts
For each ingredient, multiply the original amount by the RCF.
- Cake Flour: Original amount is 4 C. New amount is $4\times0.5 = 2$ C.
- Cocoa Powder: Original amount is 2 C. New amount is $2\times0.5=1$ C.
- Sugar: Original amount is $2\frac{1}{4}$ C. First convert $2\frac{1}{4}=\frac{9}{4}$ C. New amount is $\frac{9}{4}\times0.5=\frac{9}{4}\times\frac{1}{2}=\frac{9}{8} = 1\frac{1}{8}$ C.
- Baking Powder: Original amount is 2 t. New amount is $2\times0.5 = 1$ t.
- Baking Soda: Original amount is 1 t. New amount is $1\times0.5=0.5$ t.
- Salt: Original amount is 1 T. New amount is $1\times0.5 = 0.5$ T.
- Eggs: Original amount is 4. New amount is $4\times0.5 = 2$.
- Vanilla Extract: Original amount is 2 T. New amount is $2\times0.5 = 1$ T.
- Milk: Original amount is $1\frac{1}{3}$ C. Convert $1\frac{1}{3}=\frac{4}{3}$ C. New amount is $\frac{4}{3}\times0.5=\frac{4}{3}\times\frac{1}{2}=\frac{2}{3}$ C.
- Oil: Original amount is $2\frac{1}{2}$ C. Convert $2\frac{1}{2}=\frac{5}{2}$ C. New amount is $\frac{5}{2}\times0.5=\frac{5}{2}\times\frac{1}{2}=\frac{5}{4}=1\frac{1}{4}$ C.
- Hot Coffee: Original amount is 3 C. New amount is $3\times0.5 = 1.5$ C.
