Every day, the Perry Pet Store uses 2 bags of dog food to feed the dogs. How many days will 1/5 of a bag of dog food last?

If the Perry Pet Store uses 2 bags of dog food every day, then we can calculate how long \( \frac{1}{5} \) of a bag will last by first determining how much of a day 1 bag lasts.

- 1 day consumes 2 bags of food.
- Therefore, \( \frac{1}{2} \) of a day will consume 1 bag of food.

Now, we need to figure out how many days \( \frac{1}{5} \) of a bag will last:

\[
\text{Days for } \frac{1}{5} \text{ bag} = \frac{1}{5} \times \frac{1}{2} = \frac{1}{10} \text{ days}.
\]

So, \( \frac{1}{5} \) of a bag of dog food will last \( \frac{1}{10} \) of a day, or 0.1 days.

### Would you like more details or have any questions?

Here are 5 questions related to this problem:

1. How much food would be used in half a day?
2. What if the store used 3 bags per day? How long would \( \frac{1}{5} \) of a bag last?
3. If they reduce usage to 1 bag per day, how many days will 1 bag last?
4. How many bags would they need for 5 days of feeding?
5. What fraction of a bag is used in 1 hour?

**Tip**: When dealing with rates, always calculate the rate per unit first, like "bags per day," to scale the problem easily.
