Sometimes it is advantageous to express a value in round numbers. To round to a particular place, look at the digit immediately to the right of the one you want to round to, in this case, the tenths place. If that digit is 4, 3, 2, 1 or 0, zero it and everything to the right of it out. If that digit is 5, 6, 7, 8 or 9, increase your target digit by one and zero everything to the right of it out. If your target digit is 9, it will become a zero and increase the digit to the left of it by one.
You round to the nearest whole number.
work out
To the nearest whole number, that rounds down to 5.
Any number of 18.5 and greater will round off to 19
Any integer is already rounded to the nearest fractional part.
You round to the nearest whole number.

whole numbers have no part after the decimal point; therefore the answer is 9
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.
Any integer is already rounded to the nearest fractional part.
15 is the nearest whole number
The nearest whole number is 1.
Zero is the nearest whole number.
Some people find it easier to add or subtract whole numbers but yes, you could round to the nearest half.
7.2 = 7 ( to nearest whole number).
