Question 5 One batch of pancakes calls for \( 1 \frac{1}{4} \) cups of milk. Alston used \( 3 \frac{3}{4} \) cups of milk to make pancakes. Which multiplication equation could be used to find number of batches b of pancakes Alston made?

Alston used a total of \( 3 \frac{3}{4} \) cups of milk, which can be converted to an improper fraction as \( \frac{15}{4} \). The amount of milk needed for one batch of pancakes, \( 1 \frac{1}{4} \), can also be turned into an improper fraction: it becomes \( \frac{5}{4} \). To find the number of batches \( b \) Alston made, you can set up the multiplication equation \( \frac{5}{4}b = \frac{15}{4} \). You can solve this equation by multiplying both sides by the reciprocal of \( \frac{5}{4} \), which is \( \frac{4}{5} \). By doing so, you'll arrive at the number of batches of pancakes Alston successfully created. So, keep that math handy next time you whip up a batch of pancakes!
