Question 5 One batch of pancakes calls for \( 1 \frac{1}{4} \) cups of milk. Alston used \( 3 \frac{3}{4} \) cups of milk io make pancakes. Which multiplication equation could be used to find the number of batches b of pancakes Alston made? \( \begin{array}{l}\text { A) } 3 \frac{3}{4} b=1 \frac{1}{4} \\ \text { B) } 3 \frac{3}{4}=1 \frac{1}{4} b \\ \text { C) } b=1 \frac{1}{4}\left(3 \frac{3}{4}\right) \\ \text { D) } 3 \frac{3}{4}\left(1 \frac{1}{4}\right)=b\end{array} \)

To solve the problem, we can determine that Alston used \( 3 \frac{3}{4} \) cups of milk for a certain number of batches \( b \), each requiring \( 1 \frac{1}{4} \) cups. Therefore, the multiplication equation can represent the total cups of milk used by the number of batches multiplied by the amount of milk needed per batch. So, the equation is \( 3 \frac{3}{4} = 1 \frac{1}{4} b \), which aligns perfectly with choice B. Now, you might find it interesting to know that the basic concepts of cooking and baking often lead us to explore ratios and proportions, which are fundamental in various fields like chemistry and engineering. There's something quite magical about transforming simple ingredients into delicious pancakes! If you loved delving into measurements and cooking ratios, you might want to grab a cook book that focuses on fractions in baking. Not only will it aid in your kitchen skills, but you’ll likely impress your friends with your newfound knowledge of how to double or halve recipes with ease!
