convert 672 inches to feet, using a conversion factor

Sorry i didnt give a good description but this was the question...
::::::::::::::::::::::
The length of the longeset recorded jump made on a skateboard measured 672 inches. Use a conversion factor to find the length of this jump in feet.

I divided 12 into 672 and got 56 feet and it was right but she marked it wrong. How to you do a "conversion factor" or whatever?

You have the correct answer, numerically. (And I'm assuming you put the correct units on the answer.)

At a guess, she counted off for not using a conversion factor. To see how those work, try here. It may be that this is wrong:

. . . . .$\frac{672}{12}\,\mbox{ feet}\, =\, 56\, \mbox{ feet}$

...because you didn't show the step:

. . . . .$\frac{672\, \mbox{ inches}}{1}\, \times \, \frac{1\, \mbox{ foot}}{12\, \mbox{ inches}}\, =\, 56\, \mbox{ feet}$

I'm just guessing, though.
