    Ask your teacher about significant figures.
    It's correct to the extent that you reduce the number of sigfigs

    Yes they are equal, just like the limit for [tex]x \rightarrow \infty[/tex] of 1/x is 0.
    Just remember that it is not a matter of opinion or polling, but a mathematical identity!
