Good comment by Tito, pointing out that you may want to make sure that your frequencies are coming from a number of trials that are similar (ideally identical).
I recommend multiplying each proportion that you have by X, and setting the number of trials to X also.
If you have an identical number of trials for each variable, then X = the number of trials. You can then run your chi-squared.
If you havethere are differing numbers of trials, I assume that your ferquencies are a proportion of "successes", so I would use X = 100 to turn everything into # of successes out of 100then I'm not sure.
Hope this helps.
