Round up to the nearest hundred - 600 (because the two number after the hundred are 50 or more).
I take it the second part of the question refers to the nearest ten, as the nearest tenth would be a decimal place.
Round down to the nearest ten - 560 (because the unit is less than 5).
564 rounded to the nearest tens place is 560
While units = 564 Tenth units = 564.2 Hundreds = 564.23
564 to the nearest hundred would be 600

600. The two options are: 500 which is 564-500 = 64 away or 600 which is 600-564 = 36 away. Now pick which one is nearest.
