i have a math question how would you go about rounding 205,734,848 to the nearest billions?

In this thread, I'm using the US definition of one billion.

If it is closer to 1,000,000,000, then it rounds to 1 billion.

If it is closer to 0, then it rounds to 0 billion.

There's a simple rule for rounding, but I'm not telling until you let me know that you at least understand what I've typed so far.

You could also search Google for lessons on rounding. There are probably a googol of those to look at. :wink:

MY EDIT: Fixed my figures after misreading given value as 205 billion +

Here's what "one billion" looks like:

1,000,000,000

Your number has 0 in the billions place...which we would not normally write, but I'm going to put the 0 there....

0,205,734,848

You can see that 205,734,848 is between 0 billions and 1 billion. Which is it closer to?

Yikes! I blew it.

(I can't even blame the difference between a US billion and a UK billion, darn it.) :wink:

I will edit my original post, before Denis sees it.
