New help needed dont be gross please.. :C

19/15

Step-by-step explanation:

To solve this, we need to add 2/3 and 3/5, to do this, we need to find the LCM of 3 and 5, that is 15. We multiply 2/3 by 5/5 and 3/5 by 3/3. This gets us 10/15 + 9/15. When we add those together, we get 19/15.

9/15+10/15

19/15

I hope this helps:
