zonal statistics for rasters of different resolutions

I am working on a project where we are trying to get a statistical value for each MODIS cell (1500 m) based upon the corresponding National Land Cover Dataset (30 m) cells for all layers.

For instance a MODIS cell would contain ~ 50x50 NLCD cells, and I would like to know for each MODIS cell, what percentage of NLCD cells those are grassland. This process would need to be computed for all MODIS data and for all 21 of the NLCD layers.Obviously we would need to brak this up.

I know that zonal statistics will compute this IF the cell size is the same. But I have not been able to figure out how to accomplish this with rasters of such different resolution.

Thank you all for your help.
