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.
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).

Six to the nearest ten is ten. Three to the nearest ten is zero.
94. The nearest multiple of 6 before 567 is 564, and 564/6 = 94. However, 567/6 = 94.5
