Sometimes it is advantageous to express a value in round numbers. To round to a particular place, look at the digit immediately to the right of the one you want to round to, in this case, the ones place. If that digit is 4, 3, 2, 1 or 0, zero it and everything to the right of it out. If that digit is 5, 6, 7, 8 or 9, increase your target digit by one and zero everything to the right of it out. If your target digit is 9, it will become a zero and increase the digit to the left of it by one.

It could be 7499 rounded to the nearest 5000.
The answer depends on the extent of rounding. It could be 2501 to the nearest 5000.
7499.99... to the nearest 5000.
7499.999... to the nearest 5000
That depends what you're rounding to: To the nearest 5, 5002 To the nearest 10, 5004 To the nearest 100, 5049 To the nearest 1000, 5499 To the nearest 2500, 6249 To the nearest 5000, 7499 Rounding to anything above 5000 would not provide a result that could be 5000, so the largest whole number I can round to 5000 would be 7499.
