1. Convert the mixed numbers to improper fractions:

- For $$5 \frac{2}{5}$$:
     $$
     5 \frac{2}{5} = \frac{5 \times 5 + 2}{5} = \frac{25 + 2}{5} = \frac{27}{5}
     $$
     
   - For $$4 \frac{9}{10}$$:
     $$
     4 \frac{9}{10} = \frac{4 \times 10 + 9}{10} = \frac{40 + 9}{10} = \frac{49}{10}
     $$

2. Find a common denominator to subtract the fractions. The common denominator for 5 and 10 is 10. Convert $$\frac{27}{5}$$ to a fraction with denominator 10:
   $$
   \frac{27}{5} = \frac{27 \times 2}{5 \times 2} = \frac{54}{10}
   $$

3. Subtract the fractions:
   $$
   \frac{54}{10} - \frac{49}{10} = \frac{54 - 49}{10} = \frac{5}{10}
   $$

4. Simplify the fraction $$\frac{5}{10}$$:
   $$
   \frac{5}{10} = \frac{1}{2}
   $$

Thus, there was $$\frac{1}{2}$$ cup of milk left.
