Given the number:
672831
Round to the nearest:
Ten
Ten Thousand
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 ten, ten thousand and hundred thousand, we must determine first where ten, ten thousand and 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.
Ten = 672,831
1 is less than 5 therefore the value of the tens place which is 3 remains.
=672,830
Ten Thousand = 672,831
= 2 is less than 5 therefore the value of the ten thousands place which is 7 remains.
=670,000
Hundred Thousand = 672,831
= 7 is greater than 5, therefore the value of the hundred thousands place which 6 will be increased by 1.
= 700,000
