To round a number to a nearest place, we check the digit to the right of that place:
1- If the digit is less than 5, we round down. This means that we turn all digits to the right of our desired place to zero and leave the number as it is
2- If the digit is equal to r greater than 5, we round up. This means that we add 1 to the number in the desired position and turn all numbers after it to zeros
To know the place-value of a number, check he place value chart attached below
The given number is 672,831
1- Rounding to nearest tens:
The number in the units position is 1 which is less than 5. Therefore, we round down.
This will give us 672,830
2- Rounding to the nearest hundreds:
The number in the tens position is 3 which is less than 5. Therefore, we round down
This will give us 672,800
3- Rounding to the nearest thousands:
The number in the hundreds position is 8 which is greater than 5. Therefore, we round u
This will give us 673,000
4- Rounding to the nearest ten thousands:
The number in the thousands position is 2 which is less than 5. Therefore, we round down
This will give us 670,000
5- Rounding to the nearest hundred thousands:
The number in the ten thousand position is 7 which is greater than 5. Therefore, we round up
This will give us 700,000
Hope this helps :)
