Answer:
![3 \frac{4}{5}](https://tex.z-dn.net/?f=3%20%5Cfrac%7B4%7D%7B5%7D%20)
Step-by-step explanation:
1) Add the whole numbers first.
![3 + \frac{1}{5} + \frac{3}{5}](https://tex.z-dn.net/?f=3%20%20%2B%20%5Cfrac%7B1%7D%7B5%7D%20%20%2B%20%20%5Cfrac%7B3%7D%7B5%7D%20)
2) Join the denominators.
![3 + \frac{1 + 3}{5}](https://tex.z-dn.net/?f=3%20%2B%20%20%5Cfrac%7B1%20%2B%203%7D%7B5%7D%20)
3) Simplify.
![3 \frac{4}{5}](https://tex.z-dn.net/?f=3%20%5Cfrac%7B4%7D%7B5%7D%20)
hence, the answer is 3 4/5.
