What is 2.1 billion divided by 4?

Answer 1

0.525

Answer 2

That is 525 million. The best way to figure this out is to expand the number. Two point one billion is two billion, one hundred million.

To check this out, remember that 500 million is half of a billion and therefore 1/4 of 2 billion. Likewise, 25 million times four is 100 million. Then adding those two results, you end up with 2.1 million again.

Answer 3

525 million
