2 divided by 1 and 6/7
ale4655 [162]

This problem, as written, requires a bit of guessing regarding your intentions.  My interpretation is that you want to do this division:


    2

----------

 1  6/7

If that's correct, here's what to do:  rewrite 1  6/7 as 13/7 (an improper fraction).

Then divide:

   2

--------      This is equivalent to the multiplication (2/1)(7/13) = 14/13 (answer)

 13/7
