72.927 kwhr. Am I right DrBob222? but do I have to round off 72.927 to the nearest cents?

Math  DrBob222, Thursday, January 10, 2013 at 12:16am
Yes. It rounds to $72.93.

Math  Rina, Thursday, January 10, 2013 at 12:18am
yes, that is right! Because I kept rereading my math book and i found out it says to round off to the nearest ten cents. Thank You DrBob222!

If you are to round to the nearest 10 cents, then I would round to $72.90.

Nevermind, because 9 8s bigger than 3 of course so it round down to 90 cents.

Math  Steve, Thursday, January 10, 2013 at 10:57am
No, it rounds down to 90 cents because 3 is less than 5. 93 is closer to 90 than to 100.
