How do you round 702.9 to the nearest hundred?

Answer 1

To round off a number to the nearest hundred, consider the portion of the number that

is less than a hundred.

In this example there are no "Tens" so the portion less than a hundred is 2.9 (or 02.9).

Is 2.9 nearer to 0.0 than it is to 100.0 ?

2.9 is nearer to 0.0 so the main number is rounded down, effectively replacing the portion less than a hundred with the "100" to which it is nearer.

702.9 to the nearest 100 is 700.0

If the original number had been 752.9 then 52.9 is nearer to 100 than it is to 0.00

752.9 to the nearest 100 is therefore 800.
