Answer 1

To find the total time Whitney spends listening to her favorite podcast over a five-day period, we can express this in different ways. Let's evaluate the expressions provided:

1. **12/9 (12 ninths)**: This is not correct. It doesn't represent the total time over five days based on the given daily listening time.

2. **5×7/9 (5 times 7 ninths)**: This is correct. It represents multiplying the daily listening time by the number of days (5).

3. **35/9 (35 ninths)**: This is also correct. It represents the total time after performing the multiplication (5 × 7/9 = 35/9).

4. **5+7/9 (5 plus 7 ninths)**: This is not correct. This expression mixes whole numbers and fractions incorrectly in this context.

5. **7/9+7/9+7/9+7/9+7/9**: This is correct. It represents adding the daily listening time over five days.

The three expressions that correctly represent the time Whitney spends listening to the podcast over a five-day period are:

- **5×7/9**
- **35/9**
- **7/9+7/9+7/9+7/9+7/9**
