When you add the decimals it’s the same as regular adding. You line up the decimals and then add all the way across and when you get to the decimal carry it down
line the decimals of your numbers up in a column

to add
3.5, 3.25, and .1

(any empty place becomes a zero)

3.50
3.25
0.10

6.85 would be the total.
