1. Let the total homework be 1 unit. Lee completed $$\frac{2}{3}$$ of her homework in $$\frac{3}{4}$$ hours.
2. Her work rate is  
   $$
   \text{Rate} = \frac{\frac{2}{3} \text{ unit}}{\frac{3}{4} \text{ hours}} = \frac{2}{3} \times \frac{4}{3} = \frac{8}{9} \text{ unit per hour}.
   $$
3. To complete the entire homework (1 unit), the time required is  
   $$
   \text{Time} = \frac{1 \text{ unit}}{\frac{8}{9} \text{ unit per hour}} = \frac{9}{8} \text{ hours}.
   $$

Thus, it will take Lee $$\frac{9}{8}$$ hours to complete all her homework.
It will take Lee $$\frac{9}{8}$$ hours to complete all her homework.
