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.

1. How would you calculate the total amount of paint used?
2. What is the sum of the remaining paint in both colors?
3. How would the calculation change if more red paint was used?
4. Can you convert the remaining amounts into fractions instead of decimals?
5. What is the difference in the remaining amounts of red and white paint?

Tip: When subtracting fractions, make sure the denominators are the same before subtracting the numerators.
