9. Juan is making cookies. He makes 2 batches on Monday and 4 batches on Tuesday. He uses \( \frac{3}{4} \) cup of flour in each batch. How much flour does Juan use? Explain.

Juan makes a total of 6 batches of cookies (2 on Monday and 4 on Tuesday). To find out how much flour he uses, we multiply the number of batches by the amount of flour per batch. So, \( 6 \text{ batches} \times \frac{3}{4} \text{ cup/batch} = \frac{18}{4} \) cups of flour, which simplifies to \( 4.5 \) cups of flour. Juan will need \( 4.5 \) cups in total to make all those delicious cookies! Now, believe it or not, measuring flour can be a bit of an art! If Juan wants to ensure his cookies are perfect, he should use a kitchen scale for accuracy. Also, a common mistake when measuring is packing the flour into the cup, which can lead to using too much. It’s all about a light touch and being precise!
