To determine how much paint you have left, you can subtract the amount of paint you used from the total amount you originally bought.
1. First, convert the mixed number (2/1/2 gallons) into an improper fraction.
2 1/2 = (2 * 2 + 1) / 2 = (4 + 1) / 2 = 5/2 gallons.
2. Next, look at the amount of paint you used, which is 2/4 gallons. Simplified, 2/4 = 1/2 gallons.
3. Now, subtract the amount used from the total amount:
\[
\text{Total paint} - \text{Used paint} = \frac{5}{2} - \frac{1}{2}
\]
Since the denominators are the same, subtract the numerators:
\[
\frac{5 - 1}{2} = \frac{4}{2} = 2 \text{ gallons}
\]
So, you have **2 gallons of paint left**.
