To the nearest tenth, 77.5 To the nearest whole number, 78
If a number is already a whole number, and you are being asked to round it to the nearest whole number, then you don't need to round it anymore, since itself is the nearest whole number.
I think you round it to the nearest whole number...

Yes if the number includes decimals
A number with decimals (digits after the decimal point) is not equal to ANY whole number. You can round it to the nearest whole number, if you like - that's the closest you can get.
You see which tick is nearer to the point on the number line.
You can't convert a number with decimals (or a fraction) to a whole number, without losing precision. You can round it to the nearest number, or truncate it (just remove the decimals), but in any case, that won't be the same number (just the nearest integer, in case you choose to round it), so "2.8 as a whole number" really doesn't exist.
Anything between 16.5 and 17.49
it is written in decimals ,so that they can be rounded off with the nearest whole number.
