Answer: 1 1/0 0r 11/10
If your are trying to add 1/2 and 3/5 so you would multiply 1x5, and 2x5. Then you multiply 3x2 and 5x2. After that, you would add your answers together and write it as a fraction (5/10 + 6/10) then you should get either 11/10 or 1 1/10 . Hope this helps :)
(But if your putting it in decimal form it would be 1.1)
