To find out how many total hours Stacy studies in 5 days, we first need to calculate her daily study time for both subjects.
- Daily study time:
- Math: \( \frac{2}{6} \) hour
- Science: \( \frac{3}{6} \) hour
To get the total daily study time, we add the two times together:
\[ \text{Total daily study time} = \frac{2}{6} + \frac{3}{6} = \frac{5}{6} \text{ hours} \]
- Total study time for 5 days: Now, we multiply the daily study time by the number of days (5):
\[ \text{Total study time for 5 days} = 5 \times \frac{5}{6} = \frac{25}{6} \text{ hours} \]
Therefore, the total hours she studies in 5 days is \( \frac{25}{6} \) hours.
The correct answer is D. \( \frac{25}{6} \) hours.
