Don't overthink it. You're talking less than 10% difference in the numerator of the gearing calculation. Either accept this (and do your daughter, a non-bicyclist, a favor), or compensate by decreasing the denominator by 10% as well. Bikes are rarely undergeared, but often overgeared, in my experience.
