What are the least and greatest whole numbers that round to 3000000?

Answer 1

That depends on whether you're rounding to the nearest ten,

hundred, thousand, ten thousand, hundred thousand, or million.

Each of those rounding options produces a different answer to

this particular question.

Answer 2

The least whole number that rounds to 3,000,000 is 2,950,000. This is because when rounding to the nearest million, any number greater than or equal to 2,950,000 will round up to 3,000,000. The greatest whole number that rounds to 3,000,000 is 3,049,999. This is because any number less than 3,050,000 will round down to 3,000,000 when rounding to the nearest million.
