if we have a number that is 21,079,000 and we need to round to the nearest 100,000 then we are looking at this part of the number 21,(079),000.
the 21 million has no effect on the rounding, so treat it as rounding 79,000 to the nearest 100,000. if the question was to round 21,979,000 to the nearest 100,000 then it would be 22,000,000.
tell me what you get :)
no it would be 21,100,000
sure would :)
sorry the answer to the original question is 21,100,000. the example i used would be 22,000,000 because this has been rounded to the nearest 100,000 but in doing so we have reached another million,
