The main difference is that with whole numbers the decimal point is "hiding" (after the last digit of each whole number) whereas with decimal numbers it is clearly visible.
In both cases the numbers are added with the decimal points aligned - with whole numbers there are no digits after the decimal points so the decimal points are not written, but if they were they would be visible after the last digit of the whole numbers and they would be automatically aligned; with decimal numbers there may be a different number of digits after each decimal point so it is up to the person doing the arithmetic to ensure the decimal points are aligned.
Whole numbers don’t have a decimal point and the decimals do.

How is adding decimals similar to adding whole numbers?
Adding whole numbers is the addition of decimals where the decimal part is zero; in both cases the digits are place value aligned meaning that the decimal points, which lies between the units (or ones) and tenths columns, are aligned - in the whole number the decimal point is "hiding" at the end.
