1. **State the problem:** Daquin finished 30% of his homework in 27 minutes. We need to find how many minutes it will take him to finish the remaining 70% of his homework. 2. **Formula and explanation:** If 30% corresponds to 27 minutes, then 1% corresponds to $ \frac{27}{30} $ minutes. To find the time for the remaining 70%, multiply 70 by the time for 1%. 3. **Calculate time for 1%:** $$ \frac{27}{30} = \frac{\cancel{27}}{\cancel{30}} = 0.9 \text{ minutes} $$ 4. **Calculate time for 70%:** $$ 70 \times 0.9 = 63 \text{ minutes} $$ 5. **Answer:** It will take Daquin 63 minutes to finish the rest of his homework.
