Front teeth / Back teeth gives you the ratio.
I'd guess you'll be on something between 40/17 giving you about 2.4 turns of the rear wheel for one turn of the pedals and 48/17 giving you 2.8.
There are plenty of websites with the various gearing measures programmed in for calculation. See http://www.bikecalc.com/gear_ratios
