Because the mass never changes but the luminosity does, the mass/luminosity ratio of the galaxy will change with time. In order to find out if we can create a mass/luminosity ratio of an average of $18.10$ (from the above mass/luminosity ratios of the 26 galaxies), we have to vary the timescales, metalicty, and amount of new stars forming. At first I wanted to perform a rudimentary analysis of the IMF by using a galaxy that was very young - none of the stars had turned off the main sequence. This means that all of the stellar mass was contributing to the total luminosity of the galaxy, but the giants (which contribute the most luminosity have not yet formed). This is rudimentary only because we are assuming all the stars in the galaxy are the same age and have the same metalicy. This is not the case with real galaxies because there are many different epics of star formation throughout the galaxies lifetime. Because giants contribute the most luminosity of the galaxy, the IMF basically shows the amount of giants in a galaxy.
