Hi andyboy179,

Are you using a calculator or doing long division? If you are using a calculator, you will find that

$\displaystyle \frac{1}{6}=.166666666\overline{6}$ with repeating sixes.

To round to the 4th decimal place we would inspect the 5th decimal place to see if it is 5 or greater. Since it is, we add one more to the 4th place making it

$\displaystyle \frac{1}{6}\approx .1667$

Had the 5th place been less than 5, we would not have changed the 4th place.

That is correct!
