To determine how many gallons of gas Ethan used, you can use the formula:

$$
\text{Gallons Used} = \frac{\text{Miles Driven}}{\text{Miles per Gallon (mpg)}}
$$

Given:
- **Miles Driven** = 472.5 miles
- **Fuel Efficiency** = 22.5 mpg

Plugging in the values:

$$
\text{Gallons Used} = \frac{472.5 \text{ miles}}{22.5 \text{ mpg}} = 21 \text{ gallons}
$$

**Ethan used 21 gallons of gas.**
Ethan used 21 gallons of gas.
