629,999 rounded to the nearest hundred thousand

Given the number:

629,999

Round to the nearest hundred thousand.

Solution:

In rounding numbers, it must be taken to note that if the number is greater than or equal to 5 then the succeeding number will be added by 1, hence if the number is less than 5, then the succeeding number will remain the same.

Since we are asked to round to hundred thousand, we must determine first where hundred thousand is. The number places are as follow in an ascending order: Ones/units, tens, hundreds, thousands, ten thousands, hundred thousands, millions, hundred millions, and so on.

For decimals, the number places starts with; tenths, hundredths, thousandths, ten thousandths, hundred thousandths, and so on.

6 is located in the hundred thousands place, and before 6 we have 2, which is less than 5, therefore we will retain 6 as it is , and equate the remaining lower place values to 0.

= 600,000

Final answer:
= 600,000
