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.
1.724 to the nearest hundred is 0.
5.11 is a decimal, rounded to the nearest hundredth.
1832.2243=1800 to nearest hundred.
150 percent rounded to the nearest hundreds and written as a decimal is 15,000
0.171/6:= 1 ÷ 6= 0.1667 in decimal= 0.17
You do not, but you can add zeros to pad the decimal to show the hundred thousandths place.
165 is an integer and so is already rounded to a much greater extent.
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).
It's disconcerting to find a number with two decimal points. If that's 925123.86 it can round... To the nearest integer, 925124 To the nearest ten, 925120 To the nearest hundred, 925100 To the nearest thousand, 925000 To the nearest ten thousand, 930000 To the nearest hundred thousand, 900000
