To find out how much water Janie should bring for the 9 players, we start by calculating the total amount of water needed:
Each player needs \( \frac{1}{8} \) gallon of water. Since there are 9 players, we multiply:
\[ \text{Total water} = 9 \times \frac{1}{8} \text{ gallon} = \frac{9}{8} \text{ gallons} \]
Now we can convert \( \frac{9}{8} \) gallons into a mixed number:
\[ \frac{9}{8} = 1 \frac{1}{8} \text{ gallons} \]
Thus, Janie should bring 1 and one-eighth gallons of water for the team. The answer is:
1 and one-eighth gallons.
