Rounding Numbers
In rounding a number to nearest multiple of 10, look at the digit to the right of the number to be rounded:
- If it is 0, 1, 2, 3, or 4, retain the digit and replace the other digits that follow with zero.
- If it is 5, 6, 7, 8, or 9, add one to the digit to be rounded and replace with zeros the digits after it.
402053 rounded to the nearest thousand
[tex] \tt 3 \: - Ones \\ \tt 5 \: - Tens \\ \tt 0 \: - Hundreds \\ \tt 2\: - Thousands \\ \tt 0 \: - Ten \: Thousands \\ \tt 4 \: - Hundred \: Thousands[/tex]
Since, 2 is on hundreds place look at the right digit to be rounded. So, 0 si on right digit let's round off from 2 let's keep it 2 then replace the other digits of zero.
Therefore, 402053 is now 402000
