To find the total time Erin spends watching YouTube over a five-day period, we can express it in different ways. She watches \( \frac{8}{11} \) of an hour each day for 5 days. Therefore:
- The total time can be calculated as \( 5 \times \frac{8}{11} \).
- Another way to express this is by adding \( \frac{8}{11} \) for each of the 5 days: \( \frac{8}{11} + \frac{8}{11} + \frac{8}{11} + \frac{8}{11} + \frac{8}{11} \).
- Additionally, it may also be represented with a mixed expression of whole numbers and fractions.
Among the responses, the valid expressions that represent the time Erin spends watching YouTube over a five-day period are:
- \( 5 \times \frac{8}{11} \)
- \( \frac{8}{11} + \frac{8}{11} + \frac{8}{11} + \frac{8}{11} + \frac{8}{11} \)
- \( \frac{40}{11} \) (since \( 5 \times 8 = 40 \))
Therefore, the three expressions that apply are:
- \( \frac{40}{11} \)
- \( \frac{8}{11} + \frac{8}{11} + \frac{8}{11} + \frac{8}{11} + \frac{8}{11} \)
- \( 5 \times \frac{8}{11} \)
(Note: \( \frac{13}{11} \) and \( 5 + \frac{8}{11} \) are not correct as they do not represent the total time for 5 days.)
