2. Every day at the Aquarium, the dolphins get \( 2 \frac{1}{4} \) buckets of fish. The penguins get half of this. How many buckets do the penguins get per day?

To find out how many buckets of fish the penguins get per day, we start with the amount the dolphins receive, which is \( 2 \frac{1}{4} \) buckets. To work with this mixed number, we can convert it into an improper fraction: \[ 2 \frac{1}{4} = \frac{9}{4} \text{ (because } 2 \times 4 + 1 = 9\text{)} \] The penguins get half of what the dolphins receive: \[ \text{Penguins' share} = \frac{1}{2} \times \frac{9}{4} = \frac{9}{8} \] Now, we can convert \( \frac{9}{8} \) back into a mixed number: \[ \frac{9}{8} = 1 \frac{1}{8} \] So, the penguins get \( 1 \frac{1}{8} \) buckets of fish per day.
