Answer 1

To find the total time Erin spends watching YouTube over a five-day period, we can represent it in different ways:

1. 811 + 811 + 811 + 811 + 811: This expression clearly shows the sum of the time spent each day over five days.

2. 5 × 811: This expression represents the total time spent watching YouTube by multiplying the time spent each day (in hours) by the number of days (5).

3. 5 + 811: This expression might confuse some as it suggests an addition of whole hours (5 hours) and a fraction (811 hours), but it does not correctly represent the total time spent in consistent units (hours).

On the contrary, 4011 (which could be interpreted as 40 over 11 hours) and 1311 (13 over 11 hours) don’t meaningfully represent the total time Erin spends watching YouTube over those five days.

Thus, the three expressions that correctly represent the total time Erin spends watching YouTube over a five-day period are:

• 811 + 811 + 811 + 811 + 811
• 5 × 811
• (The expression regarding total time in hours consistent with the original format), but by nature of the options, the second two are the valid representations of time over 5 days.

It's worth noting that option 5 + 811 is not consistent due to different units (hours and fractions).

So the correct answers are:

1. 811 + 811 + 811 + 811 + 811
2. 5 × 811
3. (The fifth can be an implicit understanding not written)

If we are to strictly check based on given choices and not alter the essence, one could confidently stick to total calculations via proper multiplication or summation (1 and 2 only).
