At a pizza party, Gabby and her friends drank \( 2 \frac{1}{5} \) bottles of lemon-lime soda and \( 2 \frac{1}{5} \) bottles of cola. How much soda did they drink in all?

To find the total amount of soda they drank, we can add the amounts of lemon-lime soda and cola together. Each type of soda amounts to \( 2 \frac{1}{5} \) bottles. First, convert \( 2 \frac{1}{5} \) into an improper fraction: - \( 2 \frac{1}{5} = \frac{2 \times 5 + 1}{5} = \frac{10 + 1}{5} = \frac{11}{5} \). Now, add the two amounts of soda: - \( \frac{11}{5} + \frac{11}{5} = \frac{22}{5} \). To convert \( \frac{22}{5} \) back into a mixed number: - \( 22 \div 5 = 4\) with a remainder of \( 2\), which gives us \( 4 \frac{2}{5} \). So, Gabby and her friends drank a total of \( 4 \frac{2}{5} \) bottles of soda at the pizza party!
