This doesn't make sense, NO not that I don't know how to add fractions, but why post something like this on here? I mean the whole point of this website is to enjoy making and watching other user's videos! Not for education. You've got this all wrong.
That first problem would come out to be 5 10ths but that can be reduced down to 1 5ths, so your real answer would be 1 5ths. I use something called the backwards Z to do my fraction problems.
