When comparing whole numbers line up the numbers by place value then from the left compare the digits.
1,463,281 1,463,281 > 1,461,575
With decimals align numbers by decimal points remember to add zeros if needed. Start comparing from the left.
4. 4.000

4.317 4.317 4 < 4.317 < 4.32 Which is the least?
When rounding whole numbers and decimals underline the place you need to round to then circle the digit to the right. When the circled digit is ³ 5 bump up and change digits to the right to zeros when it is a whole number or drop them if its a decimal. When the circled digit is <5 do not change the rounding place digit.
667,935 rounded to the nearest hundred is 668,000
