1. **State the problem:**
Jenna spent $2 \frac{4}{5}$ hours on homework. The time spent on homework is $1 \frac{1}{3}$ hours more than the time spent on exercising. We need to find how many hours Jenna spent on homework and exercising combined.
2. **Convert mixed numbers to improper fractions:**
- Homework time: $2 \frac{4}{5} = \frac{2 \times 5 + 4}{5} = \frac{14}{5}$ hours.
- Difference in time: $1 \frac{1}{3} = \frac{1 \times 3 + 1}{3} = \frac{4}{3}$ hours.
3. **Find the time spent on exercising:**
Since homework time is $1 \frac{1}{3}$ hours more than exercising, we have:
$$\text{Homework} = \text{Exercising} + \frac{4}{3}$$
So,
$$\text{Exercising} = \text{Homework} - \frac{4}{3} = \frac{14}{5} - \frac{4}{3}$$
4. **Calculate the exercising time:**
Find common denominator for $\frac{14}{5}$ and $\frac{4}{3}$, which is 15.
$$\frac{14}{5} = \frac{14 \times 3}{15} = \frac{42}{15}$$
$$\frac{4}{3} = \frac{4 \times 5}{15} = \frac{20}{15}$$
Subtract:
$$\frac{42}{15} - \frac{20}{15} = \frac{22}{15}$$
So, exercising time is $\frac{22}{15}$ hours or $1 \frac{7}{15}$ hours.
5. **Find total time spent:**
Add homework and exercising times:
$$\frac{14}{5} + \frac{22}{15}$$
Convert $\frac{14}{5}$ to fifteenths:
$$\frac{14}{5} = \frac{42}{15}$$
Add:
$$\frac{42}{15} + \frac{22}{15} = \frac{64}{15}$$
Convert to mixed number:
$$\frac{64}{15} = 4 \frac{4}{15}$$
**Final answer:** Jenna spent $4 \frac{4}{15}$ hours on homework and exercising combined.
