You don't need any digits to the right of the decimal point for an estimate to the nearest hundred. The third place to the left of the decimal point is the hundreds column. The second place to the right of the decimal point is the hundredths column. the tenths and hundredthscolumn together give you changes in increments of hundredths of a unit from point 00 to point 99.

You do not, but you can add zeros to pad the decimal to show the hundred thousandths place.

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).
