Dora buys one package each of 1-pound, 2-pound, and 4-pound packages of ground beef to make hamburgers. How many \( \frac{1}{4} \)-pound hamburgers can she make? Show your work using words, pictures, or numbers.

Dora has a total of 1 pound + 2 pounds + 4 pounds of ground beef, which equals 7 pounds. To find out how many \( \frac{1}{4} \)-pound hamburgers she can make, we need to determine how many \( \frac{1}{4} \) pounds are in 7 pounds. We can do this by dividing 7 pounds by \( \frac{1}{4} \) pound: \[ 7 \div \frac{1}{4} = 7 \times 4 = 28 \] So, Dora can make 28 \( \frac{1}{4} \)-pound hamburgers with the 7 pounds of ground beef she purchased! Additionally, if we visualize this, think of each pound as consisting of 4 quarters. Thus, 7 pounds consists of 28 quarters. Each \( \frac{1}{4} \)-pound hamburger takes one quarter, resulting in a delicious total of 28 hamburgers!
