Further explanation
Rounding results on integers can be used to find estimates or determine estimates of the results of a calculation. Estimates can be used as a reference or comparison in determining the truth of the results of a calculation
To round off integers to the nearest hundreds, look at the tens


If the tens are less than 5 (1-4), then the unit number is omitted



Example: 735 ---> 700


If the tens are 5 to 9 then the tens are rounded up to 1 hundred



Example: 279 ----> 300
On multiplications between numbers 289 and 7, rounding can be made as follows:


number 7, because the value is above 5 then rounded up to 10



number 289, because the value of the number tens of 8, then rounded up to 1 hundred to 300



So the results of the multiplication become:
10 x 300 = 3000
