I was just wondering how you get the 7 at the end of the answer of 60 divided by 9. The answer is 6.66666666667

That is a good question :)

$${\frac{{\mathtt{60}}}{{\mathtt{9}}}} = {\frac{{\mathtt{20}}}{{\mathtt{3}}}} = {\mathtt{6.666\: \!666\: \!666\: \!666\: \!666\: \!7}}$$

 

Now

  

$$\\\frac{20}{3}=6\frac{2}{3}\\\\
and\\\\
\frac{2}{3}=0.66666666......\\\\$$

 

the 6's will keep going for ever and ever. If you want to cut them off at some point then the last one should be rounded up to a 7.  

 

This looks like a really good little video clip explaining how numbers are rounded off.
