Nai's dog eats \( 1 \frac{1}{5} \) cups of dog food per day. If Nai has 12 cups of dog food left, how many days can Nai feed his dog before having to buy more? A 10 days C days 5 days D 2 days

To determine how many days Nai can feed his dog with the remaining dog food, follow these steps: 1. **Convert Mixed Number to Improper Fraction:** - The dog eats \( 1 \frac{1}{5} \) cups per day. - Convert \( 1 \frac{1}{5} \) to an improper fraction: \[ 1 \frac{1}{5} = \frac{6}{5} \text{ cups per day} \] 2. **Calculate Total Days:** - Nai has 12 cups of dog food. - Divide the total cups by the daily consumption: \[ \text{Number of Days} = \frac{12}{\frac{6}{5}} = 12 \times \frac{5}{6} = 10 \text{ days} \] **Answer:** **A) 10 days**
