Answer 1

To find the total time Whitney spends listening to her favorite podcast over a five-day period, we need to multiply the daily listening time by the number of days. Since Whitney listens to her podcast for $\frac{7}{9}$ of an hour each day, we can express her five-day listening time in several ways.

Here are the options you provided:

1. 5 + $\frac{7}{9}$: This represents adding the total time to the number of days, which is not correct.
2. 5 × $\frac{7}{9}$: This represents the correct multiplication of the number of days by the daily time, which gives the total time listened over five days.
3. 359: This is not a valid expression for the time spent since it's just a number.
4. $79+79+79+79+79$: This is correct because it represents adding $\frac{7}{9}$ for each of the five days, and each $79$ is effectively the same as $\frac{7}{9}$.
5. $\frac{7}{9}+\frac{7}{9}+\frac{7}{9}+\frac{7}{9}+\frac{7}{9}$: This also accurately adds $\frac{7}{9}$ for five days, which is correct.
6. 129: Not a valid expression for the time.

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

• 5 × $\frac{7}{9}$
• $79+79+79+79+79$
• $\frac{7}{9}+\frac{7}{9}+\frac{7}{9}+\frac{7}{9}+\frac{7}{9}$

So the correct answers are the second, fourth, and fifth options you provided.
