Question

on one day in august this year, 1210000 people visited London, to the nearest 10000. what is the lowest and largest number of people that could have attended London that day?

Answer 1

The closest ten thousand to 1,210,000 is 1,210,000 itself.

To find the lowest and largest number of people that could have visited London, we need to determine the range of possible values within which 1,210,000 falls.

If we round 1,210,000 to the nearest hundred thousand, we get 1,200,000. This means that the actual number of visitors could be up to 50,000 more than 1,200,000 or up to 10,000 less than 1,200,000.

Therefore, the lowest number of people that could have visited London is:

1,200,000 - 50,000 = 1,150,000

And the largest number of people that could have visited London is:

1,200,000 + 10,000 = 1,210,000

So the lowest number of people that could have visited London is 1,150,000, and the largest number is 1,210,000.
