Lola Mina used 5 7/10 liters of red paint and 73/10 liters of white paint. If he has 85/10 liters of red paint and 10 9/10 liters of white paint, how many liters of paint remained?

To find how many liters of paint remained, we need to subtract the amount of paint used from the total amount of paint Lola Mina initially had.

### 1. Red Paint Calculation:
- **Total red paint:** \( \frac{85}{10} \text{ liters} \)
- **Red paint used:** \( 5 \frac{7}{10} = \frac{57}{10} \text{ liters} \)

Remaining red paint:
\[
\frac{85}{10} - \frac{57}{10} = \frac{85 - 57}{10} = \frac{28}{10} = 2 \frac{8}{10} = 2.8 \text{ liters}
\]

### 2. White Paint Calculation:
- **Total white paint:** \( 10 \frac{9}{10} = \frac{109}{10} \text{ liters} \)
- **White paint used:** \( \frac{73}{10} \text{ liters} \)

Remaining white paint:
\[
\frac{109}{10} - \frac{73}{10} = \frac{109 - 73}{10} = \frac{36}{10} = 3 \frac{6}{10} = 3.6 \text{ liters}
\]

### 3. Final Answer:
- **Remaining red paint:** 2.8 liters
- **Remaining white paint:** 3.6 liters

Thus, **2.8 liters** of red paint and **3.6 liters** of white paint remain.
